1.	A vessel of volume V contains a mixture os n_1 mol of nitrogen and n_2 mol of oxygen at temperature T. The molecular weights of nitrogen and oxygen are M_1 and M_2 respectively. Considering the gases are ideal, find the pressure and average molecular weight of the gas mixture.
Answer» ANSWER :`[((n_1+n_2)RT)/V,(n_1M_1+n_2M_2)/(n_1+n_2)]`
