Use your ideal gas law. 

$${P_i V_i \over n_i R T_i} = {P_f V_f \over n_f R T_f}$$

R is a constant, it cancel out. n will remain the same, it goes away. T is said to be constant, it cancels out. You're left with $$P_iV_i = P_f V_f$$

The ideal gas law is also used for the second one. 

Realize that $$n = {m \over M}$$ where m is the mass (in kg) and M is the molar mass (in kg/kmol). 

Pick any of the two states (initial or final), plug in values, and solve.
