How much carbon monoxide (IV) is contained in 4.4 grams of it? How many molecules?

In order to find the amount of a substance in a certain mass of carbon dioxide, you must first determine its molar mass.

Find the molar mass of carbon dioxide. To do this, we add up the molar masses of the atoms that enter the molecule.

M CO2 = 12 + 16 x 2 = 44 grams / mol;

Let’s find the amount of a substance by dividing the mass of a substance by its molar mass:

N CO2 = 4.4 / 44 = 0.1 mol;

One mole of a substance contains 6.022 x 10 ^ 23 molecules.

Find the number of molecules in 0.1 mol of carbon dioxide.

K CO2 = 6.022 x 0.1 x 10 ^ 23 = 6.022 x 10 ^ 22 molecules;
