In chemistry, the molar mass M is a physical property defined as the mass of a given substance (chemical element or chemical compound) divided by the amount of substance. The base SI unit for molar mass is kg/mol. However, for historical reasons, molar masses are almost always expressed in g/mol.
Similar to the first step, divide molar mass of all the Hydrogen in (NH4)2So4 by the molar mass of (NH4)2So4, then multiply it to .750, and then multiply it to avogadro's number 6.022e23 or 6.022x10^23 yay! (except for the formula unit thing, whatever it is, sawy). Source(s): PureHobo7000 Â· 8 years ago. Thumbs up.
