Answer:
The answer to your question is below
Step-by-step 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
