Find the volume and number of molecules for 15kg of nitric oxide (II)
| August 7, 2021 | education
The amount of substance n = m / M = V / Vn.u. = N / Na.
m = 15 kg = 15000 g.
M (NO) = M (N) + M (O) = 14 + 16 = 30 g / mol.
From the formula for the amount of substance, we express the volume: V = m * Vn.u. / M = 15000 * 22.4 / 30 = 11200 l.
From the formula for the amount of substance, we express the number of molecules: N = m * Na / M = 15000 * 6.02 * 10 ^ 23/30 = 3010 * 10 ^ 23.
