Calculate the volume of 32 g of methane CH4

In order to calculate what volume a certain mass of gas occupies under normal conditions, you must first determine the amount of substance in a mole. Then, using the molar volume of the gas, calculate its volume. For any gas under normal conditions. the molar volume is 22.4 l / mol (according to Avogadro’s law).

The molar mass of methane is 16 g / mol. Let’s find the amount of methane substance:

n = m / M = 32/16 = 2 mol.

Now, knowing the amount of substance, we calculate the volume:

V = n * Vm = 2 * 22.4 = 44.8 liters.

Answer: the volume of methane is 44.8 liters.
