How many grams of h20 are equivalent to 4 mole of h20?
Since the molar mass (grams per mole) of H2O is 18.02, the grams of H2O in 4 moles is 72.08g.
How many molecules of h20 are in 2.43 mol of h20?
A mole of any substance is 6.02214179×1023 (just use 6.022) molecules of it. So 1.23 moles of any substance (including water) is 1.23 x 6.022 x 1023 molecules, whatever that is...
