Question
When 6.3 g of sodium bicarbonate is added to 30 g of acetic acid solution, the residual solution is found to weigh 33 g. The number of moles of carbon dioxide released in the reaction is
Options
3
0.75
0.075
0.3
Solution
0.075
Explanation:
\[\ce{NaHCO3 + CH3COOH -> CH3COONa + H2O + CO2 ^}\]
\[\ce{6.3 g + 30 g -> 33 g + x}\]
The amount of CO2 released,
x = 3.3 g
No. of moles of CO2 released = `3.3/44` = 0.075 mol
