Answer:
9.2288 L
Explanation:
The equation of the reaction is given as;
2 Ca(NO3)2 → 2 CaO + 4 NO2 + O2
From the reaction;
2 mol of Ca(NO3)2 produces 4 mol of NO2
Converting 33.8g to Number of moles;
Number of moles = Mass / Molar mass
Number of moles = 33.8 g / 164.088 g/mol
Number of moles = 0.206 mol
2 = 4
0.206 = x
Solving for x;
x = 0.206 * 4 / 2
x = 0.412 mol
At STP;
1 mol = 22.4 L
0.412 mol = x
Solving for x;
x = 0.412 * 22.4 = 9.2288 L
