Question

What is the volume occupied by $11$g of carbon dioxide at ${27}^o$C and $20$ atm pressure?

Answer 1

According to Ideal gas equation,

$PV=nRT$

We know that, $n=\frac{givenmass}{molecularmass}$

$n=\frac{11}{44}=0.25$ moles

$V=?$

$V=\frac{nRT}{P}$

$=\frac{0.25\times 0.083\times 300}{20.265}$

$=0.307$ litre
