Question

How mamy moles of H2O are equivalent to 97.3 grams of H2O

Answer 1

Explanation:

Number of moles is defined as mass divided by molar mass.

Mathematically,       No. of moles = $\frac{mass}{molar mass}$

It is known that molar mass of water ($H_{2}O$) is 18 g/mol and it is given that mass is 97.3 grams.

Hence, calculate the number of moles of water as follows.

                        No. of moles = $\frac{mass}{molar mass}$

                                               = $\frac{97.3 g}{18 g/mol}$

                                               = 5.40 mol

Thus, we can conclude that there are 5.40 moles of H2O are equivalent to 97.3 grams of H2O.
