Question

If atomic mass of Mg atom is 24g,find the mass of 1 Mg atom​

Answer 1

To find the mass of a single Mg atom we multiply its atomic mass (24 amu) by the mass of one atomic mass unit (
`1.6605 × 10^-24` grams/amu), yielding approximately
`3.9852 × 10^-23` grams for one Mg atom.

Step-by-step explanation:

To calculate the mass of one Mg atom, given its atomic mass is 24g, we will use the concept of atomic mass units (amu). One amu is defined as 1/12th the mass of a carbon-12 atom, which approximately equates to 1.6605 × 10-24 grams per amu. Therefore, the mass of one Mg atom, which has an atomic mass of 24 amu, can be calculated by multiplying the atomic mass by the mass of one amu.

Mass of one Mg atom = 24 amu × 1.6605 × 10-24 grams/amu

This calculation results in a mass of approximately 3.9852 × 10-23 grams for one magnesium (Mg) atom.

Answer 2

4×10^-23g

Step-by-step explanation:

Given atomic mass of Mg = 24g

To find mass of 1Mg = ?

So its fix that the atomic mass of Mg 24 g is 6.022×10^23

Then the Atomic mass of 1 Mg atom is = 24 ÷ 6.022×10^23

= 4×10^-23 g
