A sample ofsea water contains 5xx10^(-3)...

A sample ofsea water contains `5xx10^(-3)g` of dissolved oxygen in 1 kg of the sample. The concentration of `O_(2)` in that sea water sample in ppm is

A

`5xx10^(-4)`

B

`5xx10^(-3)`

C

5

D

`5xx10^(-1)`

Text Solution

Verified by Experts

The correct Answer is:
C
`"Given",10^(3)g(1kg)"sample contains oxygen"=5xx10^(-3)g`
`:.10^(6)g` sample will contain oxygen
`=(5xx10^(-3)g)/(10^(3)g)xx10^(6)g=5"ppm"`
