Suppose you are performing a gas-producing reaction to experimentally determine the molar volume of the gas. Mg(s) + 2HCl(aq) →→ MgCl₂ (aq) + H₂ (g) A sample of Mg produces 21.5 mL of H₂ gas. The gas is collected over water at an atmospheric pressure of 768.6 mm Hg at 22 °C, at which the vapor pressure of water is 19.8 mm Hg. What is the experimental value for the molar volume of the hydrogen gas in L/mol?

Transcribed Image Text:Suppose you are performing a gas-producing reaction to experimentally determine the molar volume
of the gas.
Mg(s) + 2HCl(aq) → MgCl₂ (aq) + H₂ (g)
A sample of Mg produces 21.5 mL of H₂ gas. The gas is collected over water at an atmospheric
pressure of 768.6 mm Hg at 22 °C, at which the vapor pressure of water is 19.8 mm Hg.
What is the experimental value for the molar volume of the hydrogen gas in L/mol?

Transcribed Image Text:How many moles of H₂ can be formed if a 3.25 g sample of Mg reacts with excess HC1?
