## How do you calculate the percent composition of an element?

Percent Composition

- Find the molar mass of all the elements in the compound in grams per mole.
- Find the molecular mass of the entire compound.
- Divide the component’s molar mass by the entire molecular mass.
- You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.

## What is the percent composition of each element in Na2CO3?

So, Percentage of Sodium [Na] in Sodium Carbonate [Na2CO3] = 46/106 x 100 = 43.40%. Percentage of Carbon [C] in Sodium Carbonate [Na2CO3] = 12/106 x 100 = 11.32%. Percentage of Oxygen [O] in Sodium Carbonate [Na2CO3] = 48/106 x 100 = 45.28%.

## What is the percentage composition of Na3PO4?

The percent composition of Na3PO4, also known as trisodium phosphate is: Sodium 42.07 percent. Phosphorus 18.89 percent. Oxygen 39.04 percent.

## What is the percent composition of NaOH?

57.48 percent
