If 6.3g of NaHCO₃ are added 15.0g CH₃COOH solution, the residue is found to weigh 18.0 g. What is the mass of CO₂ released in the reaction?
A.4.5g
B.3.3 g✓ Correct
C.2.6 g
D.2.8 g
Explanation
According to law of conservation of mass. Mass of reactants = mass of products 6.3 15.0 18.0 xor 21.3 18.0 3.3g
