What is Molar Mass Determination of Metal about?

1) Students determined the molar mass of an unknown metal through a reaction with hydrochloric acid that produced hydrogen gas. They measured the mass of the metal, pressure and temperature of the gas, and calculated moles of gas and metal to determine the molar mass. 2) The ideal gas law relates the pressure, volume, temperature and moles of a gas. Students used this law to calculate moles of hydrogen gas from pressure, volume and temperature measurements, which then allowed calculation of moles and mola
