Question

analysis of an alloy of magnesium has 24%mg. how many atoms of mg are contained in 1gram of alloy?​

Answer 1

Explanation:

24%Mg means 24g Mg in 100g Alloy

1g of Alloy means 2.4g of Mg

Atomic mass of Mg= 24

24g of Mg is nothing but one mole Mg which has Na(Avagadro number of molecules)

2.4g will have Na/10 molecules which is equal to 6.023×10^23 / 10 = 6.023×10^22 molecules
