One kilogram of sea water contains 6 mg of dissolved `O_(2)`. The concentration of `O_(2)` in the sample in ppm is :

A

0.6

B

`6.0`

C

`60.0`

D

`2.0`

Text Solution

Verified by Experts

The correct Answer is:
B
1 kg water `=10^(6)` mg:
`10^(6)` mg water contains 6 mg `O_(2)`
`therefore` Concentration of `O_(2)` is 6 ppm.
