Answer :
Final answer:
To find the number of molecules equivalent to 98.2 g of H2O, calculate the moles first using the molar mass. Then, convert moles to molecules using Avogadro's number. The result is around [tex]3.29 x 10^24[/tex] molecules of H2O.
Explanation:
To calculate the number of molecules of H2O equivalent to 98.2 g of H2O, we need to first determine the molar mass of water, which is 18.015 g/mol.
Using the molar mass as a conversion factor, we find that there are approximately 5.45 moles of H2O in 98.2 g of H2O.
Since one mole contains 6.022 x 1023 molecules, 98.2 g of H2O is equivalent to about 3.29 x 1024 molecules of H2O.
