Question

A piece of wax weighs 18.03 g in air. A piece of metal is found to weigh 17.03 g in water. It is tied to the wax and both together weigh 15.23 g in water. Then, the specific gravity of Wax is : (A)  (18.03/17.03)  (B)  (17.03/18.03)  (C)  (18.03/19.83)  (D)  (15.03/17.83)

Tardigrade Admin · Accepted Answer

Weight of wax in air, Wa=18.03 g Weight of metal piece in water =17.03 g Weight of metal piece and wax in water =15.23 g Weight of wax in water Ww=15.23-17.03=-1.8 g Therefore, specific gravity of wax =( text weight of wax in air / text weight of wax in air - weight of wax in water ) =(18.03/18.03-(-1.8)) =(18.03/19.83)

Q. A piece of wax weighs $18.03 g$ in air. A piece of metal is found to weigh $17.03 g$ in water. It is tied to the wax and both together weigh $15.23 g$ in water. Then, the specific gravity of Wax is :

$\frac{18.03}{17.03}$

$\frac{17.03}{18.03}$

$\frac{18.03}{19.83}$

$\frac{15.03}{17.83}$
