Calculate the molecular mass of CO2

Calculate the molecular mass of CO₂

The molar mass of CO₂ is  44 g/mol

The sum of the total mass in grams of the atoms present in a molecule per mole is the molar mass/molecular weight. The molar mass unit is grams/mole.

To calculate the molar mass, add the atomic masses of all the chemical’s constituents. You can either memorise it or use the periodic table of elements to discover all of the atomic masses.

When describing atomic masses and molecular masses, another unit of mass commonly used is the Dalton (Da) or unified atomic mass unit (u). It is defined as 1 / 12  of the mass of one carbon-12 atom, and it was previously shortened as “amu.”

The following steps involve calculating the molar mass of compound;

• Find the number of individual atoms in a compound or molecule.
• Multiply the molar mass of every element.
• Add up all and assign units as grams/mole or “u’.

Let’s calculate the molar mass of CO₂;

Molar mass of Carbon = 12 g/mol

Molar mass of oxygen = 16 g/mol

                              =  [(1 × 12) + (2 16) ] g/mol.

                            = [ 12 + 32 ] g/mol

                                    = 44 g/mol

Therefore, The molar mass of CO₂ is 44 g/mol
