Question 274: Thermodynamics & KTG

Question

A vessel contains 16g of hydrogen and 128g of oxygen at standard temperature and pressure. The volume of the vessel in cm
3
is :

Accepted Answer

Total number of moles are
$$n = {n_{{H_2}}} + {n_{{O_2}}}$$
$$ = {{16} \over 2} + {{128} \over {32}}$$
= 12 moles
Using $$PV = nRT$$
$$V = {{nRT} \over P}$$
$$ = {{12 	imes 8.31 	imes 273.15} \over {{{10}^5}}}$$ m
