Calculate the mass of carbon you need to take to get 2 moles of carbon monoxide.

First, let’s write the formula for the reaction of obtaining carbon monoxide (lV)
C + O2 = CO2
From this formula, we know that n (C) = n (CO2), which means that n (C) = 2 mol
Using the periodic table, we find the molecular weight (Mr) of carbon equal to 12
The molecular weight is equal to the molar.
Mr (C) = M (C)
M (C) = 12 g / mol
Knowing the molar mass of a substance and the amount of carbon, we find its mass.
m (C) = n * M = 2 mol * 12 g / mol = 24 g
