# Find the total number of protons in 10g of calcium carbonate (CaCO3).

By Ritesh|Updated : November 6th, 2022

The total number of protons in 10g of calcium carbonate (CaCO3) is 3.0115 x 1024 protons. The positively charged particles called protons are found in the hydrogen atom's nucleus. A proton has the same mass as an atom of hydrogen.

### Calculate the Number of Moles

Step-1 Now we have to Calculate the number of moles

• The molar mass of calcium carbonate is = 100 g/mol
• A given weight of calcium carbonate is = 10g

Formula to find number of moles = Given weight/ Molar mass

• Number of moles = 10/100
• Number of moles = 0.1

Step-2 Now calculate the number of molecules using Avogadro Number

• As one mole of molecules = 6.022 x 1023 molecules
• 0.1 mole of molecules = 6.022 x 1022 molecules

Step-3 Calculating the number of Proton

• One calcium atom, one carbon atom, and three oxygen atoms make up calcium carbonate.
• The calcium atom possesses 20 protons compared to the carbon atom's 6 protons.
• Oxygen atoms have eight protons each.

Therefore, three oxygen atoms will have = 8 x 3 = 24 protons. We know the number of protons in 10g of Calcium Carbonate = the Number of protons in 6.022 x 1022 molecules. Then, we can use it to calculate

Total number of protons in 10 mg of Calcium Carbonate = Total number of protons x 6.022 x 1022

= 50 x 6.022 x 1022

= 3.0115 x 1024 protons

Hence, the Total Number Of Protons In 10g Of Calcium Carbonate (CaCO3) is 3.0115 x 1024 protons

Summary:

## Find the total number of protons in 10g of calcium carbonate (CaCO3).

Therefore the total number of protons in 10g of calcium carbonate (CaCO3) is 3.0115 x 1024 protons. The nucleus of a hydrogen atom contains protons and positively charged subatomic particles.
