A 0.100-gram magnesium metal sample was reacted with the 10.00 M HCl in a eudiometer 40.50 mL of hydrogen gas at 22.0 C was collected in the eudiometer. The hydrogen gas was collected over the water. The water level in the eudiometer was 170.0 mm above the water level in the beaker. The pressure at collection time was 770.50 mm Hg. The vapour pressure of water at this temperature is 19.10 mm Hg. (Mg= 24.3 g/mole; 1 mm Hg= 13.6 mm H2O; R= 0.082057 L atm/mol K) What is the volume in mL of this "dry" hydrogen gas at STP conditions?
