Answer from: randee56

we have to find the mass of the gas in the tank

1.00 mol of the gas occupies a volume of 24.5 L at the given temperature and pressure

this means

number of moles of gas in 24.5 L - 1.00 mol

then number of moles of gas in 170.0 L - 1.00 / 24.5 x 170.0 = 6.94 mol

molar mass of gas is 32.00 g/mol

therefore mass of gas present is - 6.94 mol x 32.00 g/mol = 222 g

mass of gas is 222 g

Answer from: kactus

Regarding the problem we will use the next formulas: concentration=mol/L and Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol) this means that the answer is Mass (g)= (1/24,5) x 170 x 32= (1/24,5) x 5440= 222,04 So the mass of gas in the tank is 222, 04 (g)
