So, it is represente in gram for final result. It can be calculated by adding up the atomic masses. The molar mass of the chemical substance is equal to the sum of the atomic mass of the individual atoms. There are 2 moles of Hydrogen and 1 moles of Oxygen. Which is the molar mass of H2O? After calculating the number of moles of the gas, we can use the relationship: Moles of the liquid = Mass in grams / Molar mass, So, Molar mass can be calculated as: Molar mass = Mass in grams / Moles of the liquid. For future reference the molar mass of water (H20) is ALWAYS 18g/mol. Molar Mass of Hydrogen(H)= 1. Water is made up of hydrogen and oxygen, with a formula of H2O. The molar mass of oxygen is the mass of one mole of oxygen. This compound is also known as Water or Dihydrogen Monoxide. Molar mass of H2O = 18.01528 g/mol. A mole can be defined as a collection of atoms whose mass is equal to the atomic mass in grams. I didn’t know that there is a quality and reliable tutoring service provider online. First you need to know what molar mass is.
