Question

A seawater sample contains 2.7 mg chl
`m^(-3)`. What is the chlorophyll concentration in units of mg
`L^(-1)`?

Answer 1

Given :

A seawater sample contains 2.7 mg chlorophyll m⁻³.

To Find :

What is the chlorophyll concentration in units of mg L⁻¹.

Solution :

We know, 1 m³ = 1000 L .

So, 1 m⁻³ = 10⁻³ L⁻¹

Concentration is :

`c = 2.7\ mg\ m^(-3)\\\\c = 2.7* 10^(-3)* \ mg\ L^(-1)\\\\c = 0.0027 \ mg\ L^(-1)\\\\c = 2.7\ \mu g \ L^(-1)`

Therefore, the chlorophyll concentration in units of mg L⁻¹ is
`2.7\ \mu g \ L^(-1)`.

Hence, this is the required solution.
