Question

The mass in grams of avogadros number of magnesium atoms is

a.243.3g

b.24.32g

c.2.342g

d.none of the above

science chemistry

Answer 1

Answer #1

One Avogadro no of atoms of any substance is called one mol of that substance.

And the mass of one Avogadro no of molecules is called Molar mass.

For Magnesium, the exact molar mass (upto four decimal places) is 24.3050 (g/mol)

In the given problem option (b) 24.32 g is the closest one.

Therefore option (b) is correct.
