WebExamples of molecular weight computations: C[14]O[16]2, S[34]O[16]2. Definitions of molecular mass, molecular weight, molar mass and molar weight. Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12) WebAug 4, 2024 · 1 mol = 22.4 L Molar mass N 2 = 28.02 g/mol Unknown mass of N 2 Step 2: Calculate. We start by determining the number of moles of gas present. We know that 22.4 liters of a gas at STP equals one mole, so: 867 L × 1 mol 22.4 L = 38.7 mol
