# Molar Mass of CO2 | Molar Mass | Explanation | FAQ

Molar mass of CO2 is determine by adding of carbon atom and oxygen atom. carbon dioxide consist one atom of carbon and two atom of oxygen. We can find molar mass of co2 by adding (both atom).

## What is molar mass?

It is define as the mass of sample of that chemical compound divided by the amount of substance in that sample. this phenomenon is called molar mass. It is measured in moles.

the molar mass of element it can represent gram atomic mass.

the molar mass of compound it can represent gram molecular mass.

the relative atomic mass of an element expressed in gram is called gram atomic mass.

### How to calculate the molar mass of CO2 (carbon dioxide)

the molecular formula of carbon dioxide is CO2. the molecular mass of a compound is the mass of one molecules of that compound.

One molecule of carbon dioxide (CO2) consists of 1 atom of carbon and 2 atoms of oxygen.

mass of one molecules of carbon dioxide is determine by addition methods.

For example – CO2 (carbon dioxide)

Mass of one atom of carbon + mass of 2 atoms of oxygen.

In other words;

Molecular mass of co2 (carbon dioxide) = molecular mass of carbon + 2 (molecular mass of oxygen).

because, carbon dioxide consist, one atom of carbon dioxide and two atom of oxygen.

So we can find according to following process like this.

molecular mass of carbon = 12

Molecular mass of oxygen = 16

Molecular mass of CO2 = 12 + (16×2)

= 12 + 32

= 44g

So, we can say that,

Mass of 1 mole of carbon dioxide (CO2) = 44g.

Molar mass of CO2 = 44g/mole.

#### 1. What is gram molecular mass?

the relative atomic mass of an compound is expressed in gram this phenomenon is called gram atomic mass.

For example – CO2 (carbon dioxide)

where, C = carbon

O2 = Oxygen = twise oxygen (O+O) =O2

So, the molecular mass of oxygen is 16

So, carbon dioxide consist one atom of carbon and 2 atom of oxygen.

It mean = O + O = O2

= 16 + 16 = 32g

this is called Gram Molecular Mass.

#### 2. What is Gram Atomic Mass?

the relative atomic mass of an element is expressed in grams this phenomenon is called gram atomic mass.

Gram atomic mass of oxygen is = 16g
