Question

Calculate the Formula unit mass of Sodium chloride and Zinc oxide. and Calculate the number of particles in 8 g of O2 molecules. answwer with procedure pls

Answer 1

Explanation:

Formula unit mass of ZnO=(Atomic mass of Zn)+(Atomic mass of O)

                                             =(65+16)u =81u

Formula unit mass of Na2O=(2×23)+16

                                              =62u

Formula unit mass of K2CO3=(2×39)+12+(3×16)

                         

                        =138u
