Question

Calculate mass of 2.5 gram atoms of magnesium (Atomic mass=24)

Answer 1

Hi, 
Mass of 1 gram atom of Mg = Molar mass of Magnesium =24 g

So, mass of 2.5 gram atoms of Mg = 24×2.5 = 60 g

Hope the answer helped you!

Answer 2

Solution:

Given,

Atomic mass of 1 gram atoms of Magnesium (Mg) = 24 g

Here,

* The chemical formula of Magnesium is (Mg). It is found in a solid state.

* Atomic mass is also known as gram atomic mass.

By using the unitary method, we can find 2.5 gram atoms of Magnesium (Mg).

= 24 g × 2.5 g = 60 g

Thus, the mass of 2.5 gram atoms of magnesium (Mg) is 60 g.
