5. Silver nitrate, AgNO3
6. Iron oxide, FeO.
7. Phosphoric acid, H2PO4
8. Sodium bicarbonate, NaHCO3
9. Acetic acid, CH3COOH
10. Sodium fluoride, NaF​​

Answer 1

what you need to do is,

you take the relative atomic mass of each element and multiply it by the no of atoms it has. do this for all the elements present, and add the values. that's it!

Step-by-step explanation:

try to do the last one by yourself, it is easy and you will be using the molecular/formula mass mostly everywhere in chemistry.
