A 0.200-g sample of cobalt metal reacted with hydrochloric acid according to the following balanced chemical equation: Co (s) + 2 HCI (ag) → CoCl2 (ag) + H2 (g) ww The volume of hydrogen gas collected over water was 87.5 mL at 20 °C and a barometer reading of 763 mm Hg. Referring to Example Exercise 1, answer following questions. 1. The adjusted ( corrected) volume of the H2 gas at STP using combined gas law is = 2. The number of moles of H2 gas is =, 3. The calculated STP molar volume for hydrogen is L/mol. %3D
