Molar Mass of a Gas:We are familiar with the pressure (P), volume (V), temperature (T), and number of moles (n) of gas in the Ideal Gas Law equation but the molar mass of the gas can also be calculated from the same equation. Like any other calculati...
This modified formula of the ideal gas equation can be used to compute the molar mass of any gas. What is the molar mass of gas at STP? The molar mass of a gas at standard temperature and pressure is computed using the ideal gas formula, which is: M = mRT\PV The standard tempera...
Mg(s) + 2HCl(aq) → MgCl 2 (aq) + H 2 (g) You will react a known mass of solid magnesium with an excess of hydrochloric acid, in a sealed vessel, and use the pressure change to calculate molar volume at STP. OBJECTIVES In this experiment, you will • Measure the gas ...
