Question

The ratio by mass for magnesium and sulphur in Magnesium sulphide is given as 3 : 4.Calculate the ratio by number of atoms for Magnesium sulphide
(Atomic mass of Mg=24, S=32) ....PLS ANSWER FAST!!!!!

Answer 1

Answer:

The ratio of Mg : S in magnesium sulphide should be 4:3 and Not 3:4.

Mg:S = 24x4 : 32x3 (multiplying by respective atomic masses)

= 96 g : 96 g

As they are reacting in 1:1 ratio of weights , their atoms will also be present in 1:1 ratio.

Thus molecular formula will be MgS
