What mass will 89.6 liters of nitrogen have?

V (N) = 89.6 liters.

Let’s determine the mass of nitrogen. We write down the solution.

We use the following formula. First, we find the amount of nitrogen substance.

n = V / Vm.

Where n is the amount of substance.

V is the volume of the substance.

Vm is the molar volume of the substance.

n = 89.6 / 22.4 = 4 mol.

Next, we find the mass of nitrogen for this we use the following formula.

n = m / M.

Where m is the mass of the substance.

M is the molar mass of the substance.

Let’s determine the molar mass of nitrogen.

M (N2) = 14 * 2 = 28 g / mol.

m (N2) = 4 mol * 28 g / mol = 112 g.

This means that the mass of 89.6 liters of nitrogen is 112 grams.

Answer: m (N2) = 112 g.
