The ideal gas constant (R) is generally ( 0.0821 \\, L \\cdot atm\/(mol \\cdot K) ).<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Plugging these values into the ideal gas law rearranged for volume ( V ), we get:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<br>V = \\frac{nRT}{P}<br>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Substituting in the values:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<br>V = \\frac{2.60 \\, mol \\times 0.0821 \\, L \\cdot atm\/(mol \\cdot K) \\times 273.15 \\, K}{1.00 \\, atm}<br>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<br>V = 58.4 \\, L<br>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, ( 2.60 \\, mol ) of any ideal gas occupies ( 58.4 \\, liters ) at STP.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Part B:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For the scientist on Venus, the pressure is defined as 1 Venusian-atmosphere, which is equivalent to 92 Earth-atmospheres. The temperature remains the same (273.15 K), and the amount of gas is 4.60 moles. Again using the ideal gas law ( V = \\frac{nRT}{P} ), we substitute the new conditions:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<br>V = \\frac{4.60 \\, mol \\times 0.0821 \\, L \\cdot atm\/(mol \\cdot K) \\times 273.15 \\, K}{92 \\, atm}<br>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">[<br>V = 0.637 \\, L<br>]<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Thus, ( 4.60 \\, mol ) of ideal gas occupies approximately ( 0.637 \\, liters ) under the conditions defined as STP on Venus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This calculation shows how significantly the conditions on Venus affect the volume of gas. At a much higher pressure, the same amount of gas occupies a much smaller volume compared to Earth&#8217;s STP. This illustrates the inverse relationship between pressure and volume (Boyle&#8217;s Law) in the ideal gas law, highlighting how extreme conditions, such as those on Venus, can lead to dramatically different physical properties.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The conditions of standard temperature and pressure STP are a temperature of 0.00 \u2218C and a pressure of 1.00 atm.
