There is a balloon filled with methane,CH4. If the mass of the methane is 68.34g, what is the volume of the balloon at 0.805 atm and a temperature of -10*C?

Question

bobpursley · Answer

PV=nRT V= nRT/P n = moles= mass/molmassCH4 change temp in C to K

Mindy · Answer

so what is the molar mass? i know that v= ? * .805/263K, but im stuck on this one???

Can't you calculate the molar mass of CH4. Look on the periodic table. Atomic mass C + 4*atomic mass H = molar mass CH4.
