# Calculate the mass of 12.04 x 10(to the power of 23) zinc oxide ZnO?

Answer from: **Tudor:***Briefly about myself : my parents are not ashamed....*

Calculate **number of moles** of zinc oxide (ZnO):

- n (ZnO) = N:Na = (12.04*10^23):(6.02*10^23) = 2 mol

Calculate **the mass of **zinc oxide (ZnO):

- m (ZnO) = n*M = 2*81 = 162 grams
