Calculate the volume occupied by 7.0 g of nitrogen gas at 27°C and 750 mm Hg pressure.

Solution

Molecular mass of nitrogen = 28
Number of moles of nitrogen (n)
$equals space fraction numerator Amount space of space nitrogen over denominator Molecular space mass end fraction space equals space 7 over 28$
$Now space space space space space space space straight P space equals space 750 space mm space equals space 750 over 760 space bar space space space space space space space space space space space space space straight T space equals space 273 space plus 27 space equals space 300 space straight K$
Applying ideal gas equation PV = nRT, we have,
$straight V space equals space nRT over straight P space equals space fraction numerator 7 space cross times space 0.0831 space cross times space 300 over denominator 28 space cross times space begin display style 750 over 760 end style end fraction space equals space 6.316 space straight L$
