Question

A sample of phosphorus chloride contains 1.4 moles of the substance how many atoms are there in the sample

Answer 1

Answer:

8.4308 x 10^23

Explanation:

In 1.4 moles there are 8.4308 x 10^23, we can calculate this by using Avogadro's constant which is 6.022 x 10^23.

1.4 x 6.022 x 10^23 will give us how many atoms there are in 1.4 moles.

Answer 2

If there are 1.4 moles then number of atoms would be 

moles * Avogadro's number 

= 1.4 × 6.022 × 10^23

atoms = 8.431 × 10^23 × 4( atoms asked )

=3.36 × 10^24.

Hope it helps!
