Answer:

M2O3

Explanation:

metal one consists of MO2... each oxygen is 25% so metal is 50 percent

formula 2 is M2O3... equally dividing the 100 percent between 5 parts... ech icygen is 20% each metal atom is 20%

thus M2O3 has 40% metal

hope it helps

Answer:

For first oxide, M=50% ,O=50%.

Molecular formula of first oxide is MO and its molecular mass is 16+x where x is the atomic mass of M.

∴(

16+x

x

)×100=50

16+x

x

=

2

1

2x=16+x

x=16

Let us determine formula of second oxide

M O

mass per 100 g 40 60

moles

60

40

16

60

Divided by 2.5 1 1.5

Converting into simple whole number 2 3

Molecular formula of second oxide is M

2

O
