A sample of phosphorus trichloride `(PCl_3)` contains 1.4 moles of the substance. How many atoms are there in the sample ?

A

4

B

5.6

C

`8.431 xx 10^23`

D

`3.372 xx 10^24 `

Text Solution

Verified by Experts

The correct Answer is:
D
1 mol of `PCl_3` contains = `4 xx 6.02 xx 10^23` atoms
1.4 mol of `PCl_3` will contain ` = 4 xx 6.02 xx 10^23 xx 1.4 `
`= 3.372 xx 10^24` atoms
