A sample of phosphorus trichloride (PCl(...

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

5.6v

C

`8.431 xx 10^(23)`

D

`3.372 xx 10^(24)`

Text Solution

Verified by Experts

The correct Answer is:
D
1 mole of `PCl_(3)` contains `4 xx 6.02 xx 10^(23)` atoms.
`therefore 1.4` moles will contain `=3.372 xx 10^(24)` atoms.
