C. TO GATHER AS MUCH INFORMATION ON THE TEXT AS POSSIBLE SO YOU CAN BETTER UNDERSTAND THE TEXT WHEN YOU READ
Answer:
Mass of produced = 32 g
Explanation:
Calculation of the moles of as:-
Mass = 82.4 g
Molar mass of = 122.55 g/mol
The formula for the calculation of moles is shown below:
Thus,
From the reaction shown below:-
2 moles of potassium chlorate on reaction forms 3 moles of oxygen gas
So,
0.67237 moles of potassium chlorate on reaction forms moles of oxygen gas
Moles of oxygen gas = 1 mole
Molar mass of oxygen gas = 32 g/mol
<u>Mass of produced = 32 g</u>
