Question

Calculate the percentage of oxygen in hydrogen peroxide compound

Answer 1

Calculate the percentage of oxygen in hydrogen peroxide compound

Answer 2

Answer:

the atomic mass of 1 atom of oxygen is 16amu so for 2 it will be 16*2=32(This is the molecular mass of oxygen) and for hydrogen the atomic mass is 1amu so for 2 it will be 1*2=2(molecular mass of hydrogen).so In H2O2 we 2 oxygen so AND 2 HYDROGEN(16*2)+(1*2)=molecular mass of H2O2

So,molecular mass of H2O2=32+2=34

percentage of oxygen=(molecular mass of oxygen divided by molecu;lar mass of H2O2)*100

(32 divided by 34)*100=94.12%
