Question

molar mass of water is18g mol^-1, what is the mass of 1 mole of water ?

Open in App

Solution

The weight of one mole of molecules is equal to the substance' mean molecular mass. Thus, one mole is equal to avogadro's number. Since, the molar mass of water is 18 g/mol so the mass of 1 mole of water is the same, i.e. 18 g/ mole.
