Question

Convert 32.6 grams of H2O to moles

Convert 22.7 grams of H2O to molecules

Answer 1

The answer to your question is below

Explanation:

a)

32.6 grams of H₂O to moles

molar mass of water = 2 + 16 = 18 g

18 g ------------------- 1 mol

32.6 g ---------------- x

x = (32.6 x 1)/18

x = 1.81 moles of H₂O

b) 22.7 grams to molecules

18 g of H₂O ----------------- 6.023 x 10²³ molecules

22.7 g of H₂O ------------- x

x = (22.7 x 6.023 x 10²³)/18

x = 7.59 x 10²³ molecules
