Question 1

How many moles of oxygen are formed when 58.6 g of KNO3 decomposes according to the following reaction? The molar mass of KNO3 is 101.11 g mol-1.

4KNO3(s) → 2K2O(s) + 2N2(g) + 5O2(g)

◦ 1.73 mol O2
◦ 0.724 mol O2
◦ 18.5 mol O2
◦ 0.290 mol O2
◦ 0.580 mol O2

Question 2

How many moles of nitrogen are formed when 58.6 g of KNO3 decomposes according to the following reaction? The molar mass of KNO3 is 101.11 g mol-1.
