Detailed explanation-1: -We have 5.2 moles of water that will contain 5.2 into 6.022 into 10, raise to power 23 molecules on solving this. We are getting number of water molecules equals to 3.13 into 10, raise to power 24 molecules.

Detailed explanation-2: -Hence, number of molecules is. 06 × 10 23 molecules.

Detailed explanation-3: -Avogadro’s Number is the number of atoms, molecules, or other objects that makes up one mole of a substance. For example: 6.022 x 1023 hydrogen atoms represent one mole of hydrogen. 6.022 x 1023 water molecules represent one mole of water.

Detailed explanation-4: -How many moles are thare in 2.35 * 1024 molecules of water? 3.9 moles QUESTION 8 How many grams does 5.60 x 1022 molecules of Si02 weigh?
