What is 2.10 and from where you guys get it? Please explain me.

W(M) =Weight of metal.
W(O)= Weight of oxygen.
E(M)=Equvalent weight of the metal.

E(M)= [ W(M)*8]/W(O).
= [1.05*8] /2.10.
= 4.

(1.05*8)/2.10 = 4.

@Ayush Sharma.

How 16 comes?

Ayush sharma said:   7 years ago
M(x)O + H(2) ------ (x)M + H(2)O
16+x g------------x g
1---------------------x/(16+x)
3.15 ----------------- 3.15x/(16+x)

3.15x/(16+x)=== 1.05.

After solving this x=8 g.
Equivalent weight =8/2 =4.

The mass of a particular substance that can combine with or displace one gram of hydrogen or eight grams of oxygen, used in expressing combining powers, especially of elements.

Any more explanations please?

Equivalent weight of an element is defined as the amount of element that combines with 8 grams of oxygen.

Here, 1.05 grams of metal combines with 2.1 grams of oxygen. So 4 grams of metal combines with 8 grams of oxygen.

Hence the Equivalent weight of metal is 4.
