To dissolve 0.9 g metal, 100 mL of 1 N $HCl$ is used. What is the equivalent weight of the metal?

• A. 7
• B. 9
• C. 10
• D. 6

Answer 1

The correct option is B 9

Number of gram equivalents of $HCl=0.1\times 1=0.1$
$\therefore$ Gram equivalents of the metal = 0.1
0.1 g equivalents of metal has a mass of 0.9 g
$\therefore$ 1 g equivalent of metal has a mass of 9 g
