Question

mass of an atom of argon atom is 6.64*10^-23. Its atomic mass is?

Answer 1

The atomic mass is 38.8 grams.

Given:

The mass of an atom of argon atom is 6.64*10^-23.

To Find:

The atomic mass.

Solution:

To find the atomic mass we will follow the following steps:

As we know,

Atomic mass is equal to the mass of 1 mole of a substance.

Also,

1 mole is equal to 6.022 × 10²³ atoms.

As given in the question, the mass of an atom of argon atom is 6.64*10^-23.

So, the atomic mass or mass of 6.022 × 10²³ = 6.022 × 10²³ × 6.64 × 10-²³ = 38.8grams.

Henceforth, the atomic mass of argon is 38.8 grams.
