If 6.3 g of `NaHCO_3` are added to 15.0 g `CH_3 COOH` solution. The residue is found to weigh 18.0g . What is the mass of `CO_2` released in this reaction.

1.3 g

8.3 g

3.3 g

10.3 g

Text Solution

Verified by Experts

The correct Answer is:

`NaHCO_(3) + CH_(3)COOH to CH_(3) COONa + H_(2)O + CO_(2)`
Initial mass = `6.3 + 15 = 21.3`
Final mass = 18 + mass of `CO_2`
According to law of conservation of mass: `21.3 = 18 +` mass of `CO_2`
Mass of `CO_(2) = 3.3 g`
