According to ChemTeam, molar volume is the volume taken up by one mole of ideal gas at a standard temperature and pressure. It has a of value of 22.414 liters per mole.
Know MoreThe molar volume depends heavily on the temperature and pressure of the environment; and, a slight variation can change the value of molar volume in all context. To calculate molar volume using the ideal gas law, the equation is PV = nRT.
P is the absolute pressure of the gas. V is the volume of the gas; and, n is the amount of gas in moles. R is the universal gas constant: 0.08206. T is the absolute temperature of the gas. Using this equation, it is easy to calculate the value for molar volume. With standard values for P and T, and an R of 0.08206, the molar volume of one mole of gas is 22.4 L.
The equation is P(1.00 atm) * V = n (1.00 mol) * R (0.08206 L atm/mol/K) * T (273 Kelvin). Using a simple math calculation, multiply 1 * .08206 * 273; and, it results in 22.40238. Then it must be divided by P or 1, to get V, or 22.40238 L, which in its most basic form is 22.4 L.

Full Answer >Potassium is a solid at standard temperature and pressure. It has a melting point at 146.3 degrees Fahrenheit and a boiling point of 1398 degrees Fahrenheit.
Full Answer >An example of a lab for finding the molar volume of a gas involves using the reaction Mg(s) + 2HCl(aq) --> MgCl2(aq) + H2(g) to find the molar volume of hydrogen gas. The lab measures the hydrogen gas produced during the reaction through displacing water, the volume of which is then computed. The lab assumes conditions of standard temperature and pressure.
