If 6.3 g of NaHCO_(3) are added to 15.0 g of CH_(3)COOH solution, the residue is found to weigh 18.0 g. The mass of CO_(2) released in the reaction is

Answer»

9.3 g
39.3 g
3.3 g
None of these

Solution :`CH_(3)COOH+NaHCO_(3) to CH_(3)COONa+H_(2)O+CO_(2) UARR`
Mass of reactants = Mass of PRODUCTS
`6.3 g + 15.0 g= 18.0 g+` Mass of `CO_(2)`
Mass of `CO_(2) = 6.3g + 15.0g - 18.0 g = 3.3 g`
