Answer 2

Answer:

The equivalent weight of metal is equal to 29.62 g/eq.

Explanation:

Given, the mass of metal = 5g

and, the mass of metal oxide = 6.35g

Then the mass of oxygen will be equal to = 6.35 - 5 = 1.35g

The equivalent weight is calculated by dividing the the atomic weight of the substance by its valency.

The atomic mass of the oxygen = 16g

The equivalent weight of oxygen = 16/2 = 8g

Consider that x is the equivalent weight of metal.

To calculate the equivalent weight of metal:-

$\frac{Eq. \; wt \; of \;metal}{Eq. \;wt \; of\; oxygen} =\frac{Weight\; of\; metal}{Weight\; of\; oxygen}$

$\frac{x}{8} =\frac{5}{1.35}$

$x=\frac{5}{1.35}\times 8$

x = 29.62 g/eq

Therefore, the equivalent weight of metal is equal to 29.62 g/eq.
