Answer : The correct expression is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
Explanation :
First we have to calculate the moles of
Now we have to calculate the moles of
The balanced chemical reaction is,
From the balanced chemical reaction we conclude that,
As, 1 mole of react to give 3 mole of
So, moles of react to give moles of
Now we have to calculate the mass of
Therefore, the correct expression for the mass of oxygen gas formed is, (150 × 3 × 31.998) ÷ (232.29 × 1) grams
