A sample of magnesium metal reacts completely with an excess of hydrocholoric 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 25 L, and the total pressure in the gas collection vessel is 0.96 atm. Calculate the mass of magnesium metal that reacted in grams. (Vapor pressure of water at 28.0 °C = 28.2 mmHg) Just give the number. The assumption is the value is in grams.

Transcribed Image Text:A sample of magnesium metal reacts completely with an excess of
hydrocholoric 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 25 L, and the total pressure in the gas collection
vessel is 0.96 atm. Calculate the mass of magnesium metal that
reacted in grams. (Vapor pressure of water at 28.0 °C = 28.2 mmHg)
Just give the number. The assumption is the value is in grams.
