When 0.0425 g of magnesium metal were allowed to react with excess hydrochloric acid, 45.80 mL of hydrogen gas were collected over water. The barometric pressure at the time was reported to be 29.78 in Hg. The temperature of the water near the mouth of the eudiometer was 25.1oC. The water level inside the tube was measured to be 25.24 cm higher than the water level in the beaker. (g) What is the molar gas volume at STP as determined...

a sample of magnesium metal reacts completely with an excess of hydrochloric acid: MG(s) + 2 HCl (aq) = MgCl2(aq) + H2(g). The hydrogen gas produced is collected over water at 28.0 C. the volume of the gas is 46 L and the total pressure in the gas collection vessel is 1.01 atm. calculate the mass of magnesium metal that reacted in grams (vapor pressure of water at 28.0 C = 28.2 mmHg)
