A compound (MO) contains 20% oxygen. find out atomic weight of M and m

1.	A compound (MO) contains 20% oxygen. find out atomic weight of M and molecular weight of MO.
Answer» $\bold\red{\underline{\underline {Answer:}}}$ An oxide of a metal (M) contains 40 % by mass of oxygen. 100 G of the oxide will CONTAIN 60 g of metal and 40 g of oxygen. Metal (M) has an ATOMIC mass of 24. 40 g of metal corresponds to 24\60 =2.5mol Oxygen has an atomic mass of 16. 60 g of oxygen corresponds to 16\40 =2.5mol Hence, the ratio of the number of moles of metal to oxygen is 1:1. $\\\\$ $❤♥ Please follow me and mark as brainliest. ♥❤$

$\bold\red{\underline{\underline {Answer:}}}$

An oxide of a metal (M) contains 40 % by mass of oxygen.

100 G of the oxide will CONTAIN 60 g of metal and 40 g of oxygen.

Metal (M) has an ATOMIC mass of 24.

40 g of metal corresponds to 24\60 =2.5mol

Oxygen has an atomic mass of 16.

60 g of oxygen corresponds to 16\40 =2.5mol

Hence, the ratio of the number of moles of metal to oxygen is 1:1.
