Question

2. If you start with 20.3 g of NH_NO3, how many grams of O, will be produced? Nuore also no​

Answer 1

Answer:

12.18g

Explanation:

You start with a mass of 20.3g of NH₄NO₃

We need to determine from this compound the mass of oxygen that is therein.

First, find the molar mass of the compound;

 NH₄NO₃ = 14 + 4(1) + 14 + 3(16)  = 80g/mol

So;

 Mass of oxygen  = $\frac{48}{80}$ x 20.3   = 12.18g

Since in a chemical reaction, mass is always conserved, 12.18g of oxygen is produced.
