We need to use the deal gas law here: PV=nRT

n = # grams / MM (MM = molar mass in g/mol) 

PV = (mass in g / MM) x RT 
P = (mass in g / MM) x RT / V 

But, d = mass in g / V 

thus, P = dRT / MM 

d = P x MM / RT=1.12atm*2 g/mol / (0.082*468.15K)=0.0584 g/L

m=d*V=0.0584 g/L * 0.00254L=1.48*10^-4 g
