Question

a mettalic oxide has 30% oxygen by mass find equivalent mass of metal and mettalic oxide​

Answer 1

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.
