Pre-Laboratory Questions 1) A 0.075 g sample of calcium is reacted with excess hydrochloric acid and it produced 48.50 mL of gas that was collected over water. If the atmospheric pressure was 756 mmHg and the temperature was 22.0°C. How many moles of the gas were produced? What value would you calculate for the gas constant, R? Ca (s)+ 2 HCl (aq) → CaCl2(aq)+ H2 (g)
