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 ………….. .

A

3

B

0.75

C

0.075

D

0.3

Text Solution

Verified by Experts

The correct Answer is:
C
`{:(NaHCO_(3), +, CH_(3) COOH, rarr, ubrace(CH_(3)COONa + H_(2)O)+, CO_(2) uarr),(6.3g,+,30g, rarr, 33g " " + x,):}`
The amount of `CO_(2)` released, x = 3.3 g
No. of moles of `CO_(2)` released = `3.3//44` = 0.075 mol
