Options:

A) 1.520

B) 0.995

C) 19.00

D) 9.00

Show Answer

Answer:

Correct Answer: D

Solution:

$\frac{w t . of metal hydroxide}{w t . of metal oxide} = \frac{E M + E O H^{-}}{E M + E O^{-}}$ $= \frac{1.520}{0.995} = \frac{x + 17}{x + 8}$ $= 1.520 x + 1.520 \times 8$ $= 0.995 x + 0.995 \times 17$

$1.520 x + 12.160 = 0.995 x + 16.915$

or $0.525 x = 4.755$

$x = \frac{4.755}{0.525} = 9$ .
