Question

To find the mass of NH₄NO₃ you multiply the atomic number by 2 for Nitrate, 4 for Hydrogen, and 3 for Oxygen. So from what i can tell, you just look at it's atomic number then multiply it by the little number next to it in the equation. What i don't understand is, why are we multiplying the nitrate by 2? is it because there are 2 Ns?

Answer 1

Answer:

yes

Explanation:
