Question

Calculate the molecular mass of the following compounds
1. NaOH
2.Mg(NO3)2
3.CaCO3
4.MgCO3
5.(NH4)2SO4

Answer 1

hope it helps...
plz. mark as brainly.....

Answer 2

1. NaOH =23+16+1=40

2.Mg(NO3)2=24+2(14+48)=148

3.CaCO3=40+12+48=100

4.MgCO3=24+12+48=84

5.(NH4)2SO4=2(14+4)+32+64=132
