How many molecules are in 25g of water?
(g/(g/mole) = moles). Here we have 25.0 g/(18.0g/mole) = 1.39 moles water (3 sig figs). Multiply 1.39 moles times the definition of a mole to arrive at the actual number of water molecules: 1.39 (moles water) * 6.02 x 1023 molecules water/(mole water) = 8.36 x 1023 molecules water.
