Hydrogen gas (H2) is generated by the following reaction. Ca(s) + 2 HCl(aq) -> CaCl2(aq) + H2(g); Ξ”H = -542.7 kJ/mol When this reaction takes place in a cylinder (fitted with a piston) containing 1.000 mol Ca(s), 542.7 kJ heat is lost to the surroundings. Because a gas in generated, work is done by the system against a constant pressure of 1.170 atm. If the internal energy decreases by 545.60 kJ, what is the change in the volume of the system in liters?
