Question

in an experiment 4 g of M2Ox oxide was reduced to 2.8 g of the metal. if the atomic mass of the metal is 56, then no of oxygen atoms in the oxide is?​

Answer 1

Solution:

Mass of oxygen in oxide

Explanation: 1 Mol M2Ox = (2 x 56 + 16 x) gm Now ,(2 x 56 + 16 x) of oxide = 112 gm metal :. 4 gm of oxide = 112 x 4/112 + 16 x gm metal But 112 x 4/112 + 16 x = 2.8(given) :. x = 3Read more on Sarthaks.com - https://www.sarthaks.com/312115/in-an-experiment-4-gm-of-m2ox-oxide-was-reduced-to-2-8-gm-of-the-metal
