Calculate the molecular mass of carbon monoxide (CO) by adding the atomic mass of carbon and the atomic mass of oxygen. Show your work.
In chemistry, the mole (mol) is defined as an amount of a substance that contains 6.02x 10³ particles of that substance. This number, called Avogadro's number, is special because this number of particles has a mass in grams that is equal to the mass in universal mass units of a single particle of the substance. Question How do scientists find the molecular mass and molar mass of a substance? Calculate The molecular mass of a molecule is the sum of the masses of each atom in the molecule. The unit of mo- lecular mass is the universal mass unit (u). For example, the atomic mass of iron is 55.85 u, the atomic mass of carbon is 12.01 u, and the atomic mass of oxygen is 16.00 u.
