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

12.18g

Step-by-step 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 =
`(48)/(80)` x 20.3 = 12.18g

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