Question

5 g of metal oxide was reduced to 3.4 g of the metal .if the gram atomic mass of the metal is 51 gmol-1 then the formula of the metal oxide is ? options are 1)MO 2)M2O3 3) M2O 4) M2 O5​

Answer 1

Explanation:

⇒2×56+x×16⟶2×56

⇒2×56+x×16⟶2×56⇒4×2×56=2.8(2×56+x×16)

⇒2×56+x×16⟶2×56⇒4×2×56=2.8(2×56+x×16)⇒x=1648

⇒2×56+x×16⟶2×56⇒4×2×56=2.8(2×56+x×16)⇒x=1648∴ Number of oxygen atoms in oxide

⇒2×56+x×16⟶2×56⇒4×2×56=2.8(2×56+x×16)⇒x=1648∴ Number of oxygen atoms in oxidex=1648.
