Zinc metаl is аdded tо hydrоchlоric аcid to generate hydrogen gas, which is collected over a liquid whose vapor pressure is the same as pure water at 20.0°C (18 torr). The volume of the gas mixture is 1.7 L and its total pressure is 0.810 atm.Determine the number of moles of hydrogen gas present in the sample.
