Question

The molar mass of a metallic oxide is 40 .find equivalent mass of element
​

Answer 1

Answer:

please Mark As Brainliest

Explanation:

% of oxygen us metal oxide =40%

Thus % of metal =100−40=60%

Let us consider the mass of metal oxide to be 100 g

Eq wt of metal =

Mass of oxygen

Mass of metal

×Eq.wt of oxygen

⇒ Eq. wt of metal =

40

60

×8=12

Thus Equivalent weight of metals is 12.

Answer 2

Explanation:

ANSWER

% of oxygen us metal oxide =40%

Thus % of metal =100−40=60%

Let us consider the mass of metal oxide to be 100 g

Eq wt of metal =
