Question

How many moles does 24g of mg contain ?

Answer 1

Answer:

1 mole of mg atom has 6.022×10^23 atoms its atomic mass is 24g. So 12g will have 24g =6.22×10^23

Answer 2

There are 2 moles in 24 g of Mg.

Explanation:

The number of moles is given by :

$n=\dfrac{m}{M}$

Here,

m is the given mass

M is the molar mass or atomic mass, M = 12

We need to find the number of moles in 24 g of Mg. So,

$n=\dfrac{24}{12}=2\ mole$

So, there are 2 moles in 24 g of Mg. Hence, this is the required solution.
