Webd = mP nRT = ( m n) P RT d = m P n R T = ( m n) P R T. The ratio m / n is the definition of molar mass, ℳ: M = m n ℳ = m n. The density equation can then be written d = MP RT d = ℳ P R T. This relation may be used for calculating the densities of gases of known identities at specified values of pressure and temperature as demonstrated in ... WebOct 5, 2024 · Massa 1,5 mol C = 1,5 mol × 12 g mol–1 = 18 g. 3. Ar Fe = 56 sma, Jadi, massa molar Fe = 56 g mol–1. m = 9,3 × 1023 g. 4. Massa molar CO2 = 44 g mol–1. …
