Question

An oxide of metal m has 40% by mass of oxygen metal m has atomic mass of 24 temperature formula

Answer 1

Explanation:

Hey mate

Here's ur ans

Since oxygen is40

So metal is 60

Equivalent wts r equal in the rxn

M O

60 40

So...given wt divided by n factor

60/x = 40/8

X= 12

Answer 2

Answer:

Explanation:

let the. 100g

then O is 40g

and (100-40)g =60g of metal

given mass of M/atomic mass : given mass of O/atomic mass

M. : O

60/24 :40/16

30/12:20/8

15/6 :10/4

5/2. :5/2

The ratio is 1:1 then formula is MO

Hope it helps you...
