How many molecules are there in 9.34 grams of water?

Answer 1

Assuming the question refers to LiCl (Lithium chloride) which has a molecular weight 42.39.

Avogadro's constant states there are 6.022 141 79x1023 molecules per mole

9.34 g LiCl is 9.34/42.39 mole (0.220 mole) LiCl

The number of molecules is therefore 6.022 141 79x1023x 0.220 =1.326x1023 molecules

Answer 2

A lot. 9.34g divided by 18g/mol (the molar mass of water) gets you about 0.52 moles, times Avogadro's number of 6.02x1023 = 3.13x1023 molecules.

Answer 3

There are approximately 5.55 x 10^22 molecules of water in 9.34 grams.
