respect the rules for significant figures:<\/p>\n\n\n\n<p><strong>a. 64 mm to m<\/strong><\/p>\n\n\n\n<p>To convert millimeters (mm) to meters (m), we use the conversion factor:<br>1 m = 1000 mm.<br>So, 64\u2009mm\u00d71\u2009m1000\u2009mm=0.064\u2009m64 \\, \\text{mm} \\times \\frac{1 \\, \\text{m}}{1000 \\, \\text{mm}} = 0.064 \\, \\text{m}64mm\u00d71000mm1m\u200b=0.064m.<br><strong>Significant figures<\/strong>: 64 has 2 significant figures, so the answer is <strong>0.064 m<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>b. 0.042 L to \u03bcL<\/strong><\/p>\n\n\n\n<p>To convert liters (L) to microliters (\u03bcL), we use the conversion factor:<br>1 L = 10610^6106 \u03bcL.<br>So, 0.042\u2009L\u00d7106\u2009\u03bcLL=42,000\u2009\u03bcL0.042 \\, \\text{L} \\times 10^6 \\, \\frac{\\mu L}{L} = 42,000 \\, \\mu L0.042L\u00d7106L\u03bcL\u200b=42,000\u03bcL.<br><strong>Significant figures<\/strong>: 0.042 has 2 significant figures, so the answer is <strong>42,000 \u03bcL<\/strong> (2 significant figures).<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>c. 1.9 kg to g<\/strong><\/p>\n\n\n\n<p>To convert kilograms (kg) to grams (g), we use the conversion factor:<br>1 kg = 1000 g.<br>So, 1.9\u2009kg\u00d71000\u2009gkg=1900\u2009g1.9 \\, \\text{kg} \\times 1000 \\, \\frac{g}{kg} = 1900 \\, \\text{g}1.9kg\u00d71000kgg\u200b=1900g.<br><strong>Significant figures<\/strong>: 1.9 has 2 significant figures, so the answer is <strong>1900 g<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>d. 0.31 dL to L<\/strong><\/p>\n\n\n\n<p>To convert deciliters (dL) to liters (L), we use the conversion factor:<br>1 dL = 0.1 L.<br>So, 0.31\u2009dL\u00d70.1\u2009LdL=0.031\u2009L0.31 \\, \\text{dL} \\times 0.1 \\, \\frac{L}{dL} = 0.031 \\, \\text{L}0.31dL\u00d70.1dLL\u200b=0.031L.<br><strong>Significant figures<\/strong>: 0.31 has 2 significant figures, so the answer is <strong>0.031 L<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>e. 0.75 mol to mmol<\/strong><\/p>\n\n\n\n<p>To convert moles (mol) to millimoles (mmol), we use the conversion factor:<br>1 mol = 1000 mmol.<br>So, 0.75\u2009mol\u00d71000\u2009mmolmol=750\u2009mmol0.75 \\, \\text{mol} \\times 1000 \\, \\frac{mmol}{mol} = 750 \\, \\text{mmol}0.75mol\u00d71000molmmol\u200b=750mmol.<br><strong>Significant figures<\/strong>: 0.75 has 2 significant figures, so the answer is <strong>750 mmol<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>f. 74.0 \u00b0F to K<\/strong><\/p>\n\n\n\n<p>To convert Fahrenheit (\u00b0F) to Kelvin (K), we first need to convert Fahrenheit to Celsius and then to Kelvin.<br>The conversion from Fahrenheit to Celsius is:<br>C=(F\u221232)\u00d759C = (F &#8211; 32) \\times \\frac{5}{9}C=(F\u221232)\u00d795\u200b.<br>So for 74.0 \u00b0F:<br>C=(74.0\u221232)\u00d759=42.0\u00d759=23.33\u2009\u00b0CC = (74.0 &#8211; 32) \\times \\frac{5}{9} = 42.0 \\times \\frac{5}{9} = 23.33 \\, \u00b0CC=(74.0\u221232)\u00d795\u200b=42.0\u00d795\u200b=23.33\u00b0C.<br>Then, we convert Celsius to Kelvin using:<br>K=C+273.15K = C + 273.15K=C+273.15.<br>So,<br>K=23.33+273.15=296.5\u2009KK = 23.33 + 273.15 = 296.5 \\, \\text{K}K=23.33+273.15=296.5K.<br><strong>Significant figures<\/strong>: 74.0 has 3 significant figures, so the answer is <strong>296.5 K<\/strong>.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><strong>Summary of answers with correct significant
