Question

What is the density of Carbon Dioxide gas at Standard Temperature and Pressure and 20 degree Celsius and 735 millimeter Hg?

Note: density = mass/Volume       n = mass/molar mass 

Answer 1

$Density=$ $Mass\over Volume$

$V=$ $nRT\over p$

$=$ $({1\times 62400\times 293})\over735$ $24 875.1 ml.=24.8751 L.$

$density=$ $44\over 24.8751$ $=1.7688g/L$
