Explanation is:<\/mark><\/strong><\/p>\n\n\n\n<p>Here are the solutions for your conversion and scientific notation questions:<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">1. <strong>28000000000 mg into Oz (scientific notation)<\/strong><\/h3>\n\n\n\n<p>To convert milligrams (mg) to ounces (oz), we use the conversion factor:<\/p>\n\n\n\n<p>1 oz = 28,349.5 mg. 28000000000\u2009mg\u00d7(1\u2009oz28349.5\u2009mg)=987.0\u2009oz28000000000 \\, \\text{mg} \\times \\left( \\frac{1 \\, \\text{oz}}{28349.5 \\, \\text{mg}} \\right) = 987.0 \\, \\text{oz}28000000000mg\u00d7(28349.5mg1oz\u200b)=987.0oz<\/p>\n\n\n\n<p>Now, in scientific notation: 987.0=9.87\u00d7102\u2009oz.987.0 = 9.87 \\times 10^2 \\, \\text{oz}.987.0=9.87\u00d7102oz.<\/p>\n\n\n\n<p>So, <strong>28000000000 mg = 9.87 x 10\u00b2 oz<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">2. <strong>3600 km\/hr into m\/s (scientific notation)<\/strong><\/h3>\n\n\n\n<p>To convert kilometers per hour (km\/h) to meters per second (m\/s), use the following conversion factors: 1\u2009km=1000\u2009mand1\u2009hr=3600\u2009s.1 \\, \\text{km} = 1000 \\, \\text{m} \\quad \\text{and} \\quad 1 \\, \\text{hr} = 3600 \\, \\text{s}.1km=1000mand1hr=3600s.<\/p>\n\n\n\n<p>So, 3600\u2009km\/h\u00d7(1000\u2009m1\u2009km)\u00d7(1\u2009hr3600\u2009s)=1000\u2009m\/s.3600 \\, \\text{km\/h} \\times \\left( \\frac{1000 \\, \\text{m}}{1 \\, \\text{km}} \\right) \\times \\left( \\frac{1 \\, \\text{hr}}{3600 \\, \\text{s}} \\right) = 1000 \\, \\text{m\/s}.3600km\/h\u00d7(1km1000m\u200b)\u00d7(3600s1hr\u200b)=1000m\/s.<\/p>\n\n\n\n<p>In scientific notation, this is: 1000=1.0\u00d7103\u2009m\/s.1000 = 1.0 \\times 10^3 \\, \\text{m\/s}.1000=1.0\u00d7103m\/s.<\/p>\n\n\n\n<p>So, <strong>3600 km\/hr = 1.0 x 10\u00b3 m\/s<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">3. <strong>6000 KL into cm\u00b3 (scientific notation)<\/strong><\/h3>\n\n\n\n<p>To convert kiloliters (KL) to cubic centimeters (cm\u00b3), use: 1\u2009KL=1,000,000\u2009cm3.1 \\, \\text{KL} = 1,000,000 \\, \\text{cm}^3.1KL=1,000,000cm3.<\/p>\n\n\n\n<p>So, 6000\u2009KL=6000\u00d71,000,000=6\u00d7109\u2009cm3.6000 \\, \\text{KL} = 6000 \\times 1,000,000 = 6 \\times 10^9 \\, \\text{cm}^3.6000KL=6000\u00d71,000,000=6\u00d7109cm3.<\/p>\n\n\n\n<p>Therefore, <strong>6000 KL = 6.0 x 10\u2079 cm\u00b3<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">4. <strong>508000000000 nm into Inches (scientific notation)<\/strong><\/h3>\n\n\n\n<p>To convert nanometers (nm) to inches, use: 1\u2009inch=25.4\u00d7106\u2009nm.1 \\, \\text{inch} = 25.4 \\times 10^6 \\, \\text{nm}.1inch=25.4\u00d7106nm.<\/p>\n\n\n\n<p>So, 508000000000\u2009nm\u00d7(1\u2009inch25.4\u00d7106\u2009nm)=20,000\u2009inches.508000000000 \\, \\text{nm} \\times \\left( \\frac{1 \\, \\text{inch}}{25.4 \\times 10^6 \\, \\text{nm}} \\right) = 20,000 \\, \\text{inches}.508000000000nm\u00d7(25.4\u00d7106nm1inch\u200b)=20,000inches.<\/p>\n\n\n\n<p>In scientific notation: 20000=2.0\u00d7104\u2009inches.20000 = 2.0 \\times 10^4 \\, \\text{inches}.20000=2.0\u00d7104inches.<\/p>\n\n\n\n<p>Thus, <strong>508000000000 nm = 2.0 x 10\u2074 inches<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">5. <strong>-31 \u00b0F into Kelvin (\u00b0K)<\/strong><\/h3>\n\n\n\n<p>To convert Fahrenheit (\u00b0F) to Kelvin (\u00b0K), use the formula: K=59\u00d7(\u00b0F\u221232)+273.15.K = \\frac{5}{9} \\times (\u00b0F &#8211; 32) + 273.15.K=95\u200b\u00d7(\u00b0F\u221232)+273.15.<\/p>\n\n\n\n<p>Substitute -31 \u00b0F into the equation: K=59\u00d7(\u221231\u221232)+273.15=59\u00d7(\u221263)+273.15=\u221235+273.15=238.15\u2009K.K = \\frac{5}{9} \\times (-31 &#8211; 32) + 273.15 = \\frac{5}{9} \\times (-63) + 273.15 = -35 + 273.15 = 238.15 \\, \\text{K}.K=95\u200b\u00d7(\u221231\u221232)+273.15=95\u200b\u00d7(\u221263)+273.15=\u221235+273.15=238.15K.<\/p>\n\n\n\n<p>So, <strong>-31 \u00b0F = 238.15 K<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">6. <strong>103 \u00b0K into Fahrenheit (\u00b0F)<\/strong><\/h3>\n\n\n\n<p>To convert Kelvin (\u00b0K) to Fahrenheit (\u00b0F), use the formula: \u00b0F=95\u00d7(K\u2212273)+32.\u00b0F = \\frac{9}{5} \\times (K &#8211; 273) + 32.\u00b0F=59\u200b\u00d7(K\u2212273)+32.<\/p>\n\n\n\n<p>Substitute 103 K into the equation: \u00b0F=95\u00d7(103\u2212273)+32=95\u00d7(\u2212170)+32=\u2212306+32=\u2212274\u2009\u00b0F.\u00b0F = \\frac{9}{5} \\times (103 &#8211; 273) + 32 = \\frac{9}{5} \\times (-170) + 32 = -306 + 32 = -274 \\, \\text{\u00b0F}.\u00b0F=59\u200b\u00d7(103\u2212273)+32=59\u200b\u00d7(\u2212170)+32=\u2212306+32=\u2212274\u00b0F.<\/p>\n\n\n\n<p>Therefore, <strong>103 \u00b0K = -274 \u00b0F<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h3 class=\"wp-block-heading\">7. <strong>Write the number 0.000000302 \u00d7 10 in standard
