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

A. 3
B. 0.75
C. 0.075
D. 0.3

Answer

c

Explanation

`{:(NaHCO_(3),+,CH_(3)COOH,to, ubrace(CH_(3)COONa+H_(2)O) ,+,CO_(2)uarr),(6.3g,+,30g,to," "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
