How many moles are in 59.75 grams of water?

3.32 moles

Explanation:

Water has a chemical formula of H2O.

Now given that:

Number of moles = ?

Mass in grams = 59.75 grams

Molar mass of water H2O = ?

Use the atomic mass of hydrogen = 2g, Oxygen = 16g

So, H2O = (2 x 1) + 16

= 2 + 16 = 18g/mol

Recall that:

Number of moles = (Mass in grams/ Molar mass)

No. of moles = 59.75 grams / 18g/mol

= 3.32 moles

Thus, there are 3.32 moles of water present
