a sample of iron reated with hydrochloric acid. the liberated hydrogen occupied 40.1ml when collected over water at 27 degree celsus at a barometric pressure of 750 torr. what is the mass of the sample of iron? ( Because of the collection of gas over water, the vapor pressure of the water must be subtrated from the barometric pressure to find the pressure of the hydrogen gas)
