The moles of water in 125 grams are 6.94 mol.
Moles can be defined as the ratio of the weight to the molecular weight.
Moles = [tex]\rm \dfrac{weight}{molecular\;weight}[/tex]
The given weight of water = 125 grams.
The molecular weight of water = 2 [tex]\times[/tex] molecular weight of Hydrogen + Molecular weight of oxygen
= 2 [tex]\times[/tex] 1 + 16 g/mol
= 2 + 16 g/mol
= 18 g/mol
Substituting the values in the moles equation:
Moles of water = [tex]\rm \dfrac{125\;g}{18\;g/mol}[/tex]
Moles of water = 6.94 mol.
The moles of water in 125 grams are 6.94 mol.
