Question

A sample of zinc oxide contains 80.25% of zinc . calculate the equivalent mass of zinc

Answer 1

Answer:

don't know sorry I can't

Answer 2

Answer:

equivalent mass of zinc is 32.5

Explanation:

mass of oxygen = 100 - 80.25

                          = 19.75 g

Equivalent mass of zinc oxide = 80.25 / 19.75 * 8

                                                  = 32.5 (it does not possess any unit)
