What is the molar mass of Na3PO4?
Explanation: The molar mass of sodium phosphate is Mr = (3×23)+31+(4×16) = 164g/mol. Now consider 1 mole of Na3PO4 which has a mass of 164g: 3×23 = 69g is sodium, 31g is phosphorous, 4×16 = 64g is oxygen. Therefore the percentage composition of each element is:
What is the percent composition of N A3P O4?

How do you find the percent composition of a compound by weight?
mass percent = (mass of solute / mass of solution) x 100% The units of mass are typically grams. Mass percent is also known as percent by weight or w/w%. The molar mass is the sum of the masses of all the atoms in one mole of the compound. The sum of all the mass percentages should add up to 100%.
What is the percent composition of h2so4?
Percent composition of each element in sulfuric acid: Hydrogen% = (2.016/98.07) × 100 = 2.0556% Sulfur% = (32.06/98.07) × 100 = 32.69% Oxygen% = (63.996/98.07) × 100 = 65.25%
Is mass percent the same as percent composition?
No both are different in percent composition we have to calculate the percentage of element present in a molecule. while in mass percentage we have to calculate the mass in grams of solute dissolved in 100 gram of solution.
