Convert 32.6 grams of H2O to moles

Convert 22.7 grams of H2O to molecules

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

∠cbe and ∠deb are same-side interior angles.
