WebC. The number of grams in the molar mass of an element is not the same as the atomic number. D. When calculating molar mass of a chemical compound, it states how many grams are in one mole of a substances 7. What is the molarity of a solution of 10% by mass cadmium sulfate, cdso4 (molar mass? 8. 1. Compute the molar mass of sodium … WebThe mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12. Avogadro's number (Equation ) like any pure number, is dimensionless. However, it also defines the mole, so we can also express NA as 6.02 × 1023 mol–1; in this form, it is properly known as Avogadro's ...
