Interpretation:

The mass of the given sample of water is to be determined.

Concept Introduction:

The characteristic mass of a compound is considered formula mass of that compound, which is obtained by adding the atomic masses of all the atoms present in its formula unit.

The formula mass of a compound in amu is considered numerically equal to its molar mass in gram/mol.

### Explanation of Solution

Given information: 2.55 moles of water

The molar mass of 1mole water is calculated as follows:

molarmass of H2O=2(1.01g/mol)+(16.00g/mol)=2.02g/mol+16
