Question

Calculate the amount in moles in each of the following quantities:
2.997x10^25 atoms of vanadium​

Answer 1

Answer:

Given atoms of vanadium = 2.997*10²⁵

One mole of vanadium has = 6.022*10²³atoms

No. of moles = (2.997/6.022) . (10²⁵⁻²³)

= 0.497*10²

Hope this helps.

Answer 2

The answer is 49.6 moles of Vanadium

GIVEN

Number of atoms of vanadium = 2.997 × 10²⁵

TO FIND

The number of moles

SOLUTION

The above problem can be simply solved as follows;

Applying Avogadro's law

6.022 × 10²³ atoms of Vanadium = 1 mole of Vanadium.

1 atom = 1/(6.022 × 10²³) moles

Therefore,

2.99 × 10²⁵ atoms = (2.997 × 10²⁵)/6.022 × 10²³

= 0.496 × 10²

= 49.6 moles

Hence, The answer is 49.6 moles of Vanadium
