Question

determine the mass of a gas occupying 94.5ml volume at NTP. (molar mass of the gas is 52.9g) ?

Answer 1

22400 ml (or 22.4 L) of gas at STP = 1 mole

so ,

94.5 ml of gas at STP = 94.5/22400 ml = 0.0042 mol

Molecular Mass (MM) = Mass of Gas / Number of moles of gas

such that ,

MM = 0.2231/0.0042 = 52.89 mol ≈ 52.9 mol

hence , ur answer is correct

congrats
