How many atoms are there in 0.228 moles of water?

Question

using dimensional analysis?

Answer 1

Calculate number of molecules of water using avogradro's number 6.022 x 10²³

.228 moles of water x 6.022 x 10²³ molecules of water / mole = 1.37 x 10²³ molecules of water.

3 atoms per one molecule of water, therefore convert molecules of water to atoms in the calculated quantity of water molecules.

3 atoms/ molecule of water x 1.37 x 10²³ molecules of water = 4.12 x 10²³ atoms in .228 moles of water!

WOW thats a lot! about one swallow !
