Solution:

Given P = 750 mm $ =\frac{750}{760} $ atm $ V=?w=7.0g $ $ T={{27}^{o}}C=27+273=300\text{ }K $ $ R=0.0821 $ , Molecular wt $ (M)=28 $ According to ideal gas equation, $ PV=\frac{w}{M}\times R\times T $ $ V=\frac{w\times R\times T}{P\times M} $ $ V=\frac{7\times 760\times 0.0821\times 300}{28\times 750} $ $ =\frac{1308772}{21,000} $ $ =6.232L $
