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 :

$c = 2.7\ mg\ m^{-3}\\\\c = 2.7\times 10^{-3}\times \ mg\ L^{-1}\\\\c = 0.0027 \ mg\ L^{-1}\\\\c = 2.7\ \mu g \ L^{-1}$

Therefore, the chlorophyll concentration in units of mg L⁻¹ is $2.7\ \mu g \ L^{-1}$.

Hence, this is the required solution.
