Question

If you have 500 g of LiClO4, then how many liters of oxygen will the system make at the station’s standard operating conditions, a pressure of 101.5 kPa and a temperature of 21°C? Please show how you got this.

Answer 1

You need to first find moles of O2 that would be formed.
Moles of LiClO4 = 500/(7+35.5+64)=4.69
One moles of LiClO4 would produce 2 moles of O2 hence you have 9.38.
Apply ideal gas equation
PV=nRT.
