Answer:
1.81 g of Benzoic Acid
Solution:
The balance chemical equation is as follow,
C₇H₅O₂Na + HCl → C₇H₆O₂ + NaCl
According to equation,
144.11 g (1 mole) C₇H₅O₂Na produces = 122.12 g of C₇H₆O₂
So,
2.14 g of C₇H₅O₂Na will produce = X g of C₇H₆O₂
Solving for X,
X = (2.14 g × 122.12 g) ÷ 144.11 g
X = 1.81 g of C₇H₆O₂
