Formula of carbon monoxide (IV) CO2. Let’s find its mass by the formula m = n * M = 1.5 mol * 44 g / mol = 66 g (M = 12 + 16 * 2 = 44 g / mol – molar mass, determined by the periodic table). The volume can be found by the formula V = n * Vm, where Vm = 22.4 l / mol is the molar volume, a constant value for all gases under normal conditions. V (CO2) = 1.5 mol * 22.4 l / mol = 33.6 l.
Answer: weight 66 g, volume 33.6 liters.
