An engineer wants to estimate the mass of gas that is present in a tank. she knows that 1.00 mol of the gas occupies a volume of 24.5 l at the set temperature and pressure. if the volume of the tank is 170.0 l and the molecular weight of the gas is 32.00 g/mol, what is the mass of gas in the tank

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

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

i think a, hope it .
