How many H2O molecules are in 183.2 grams of H20 gas?

There are molecules present in 183.2 grams of gas.

Explanation:

Given: Mass = 183.2 g

Number of moles is the mass of substance divided by its molar mass.

As molar mass of water is 18 g/mol. Therefore, moles of are calculated as follows.

According to the mole concept, there are molecules present in one mole of a substance.

Hence, molecules present in 10.17 moles are calculated as follows.

Thus, we can conclude that there are molecules present in 183.2 grams of gas.
