Answer: 3.49x 10^25 molecules H2O
Explanation: To find the number of molecules of H2O we will use the relationship between moles and Avogadro's Number.
57.9 moles H2O x 6.022x10²³ moles H2O / 1 mole H2O
= 3.49x10^25 molecules H2O
Cancel out the moles of H2O.

57.9 moles of H2O contains 3.48 * 10^25 molecules
Explanation:
A mole of any substance contains 6.022 x 10^23 molecules. This is the Avogadro's number which is the number of particles in C-12. To find number of molecules in 57.9 moles of H2O, multiply the Avogadro's number by 57.9
⇒ 57.9 * 6.022 x 10^23 = 348.67 * 10^23
= 3.48 * 10^25 molecules
