Step-by-step explanation:

a)
n = (PV)/(RT) = \frac{(1.8×10^7\:\text{Pa})(3\:\text{L})}{(8310\:\text{L•Pa/mol•K})(300\:\text{K})}


\:\:\:\:\:\:\:= 21.7\:\text{mol}

b)
P = (nRT)/(V)


\:\:\:\:\:\:\:\:\:= \frac{(50\:\text{mol})(8310\:\text{L•Pa/mol•K})(300\:K)}{(3\:L)}


\:\:\:\:\:\:\:\:\:=4.2×10^7\:\text{Pa}
