Question 1

Marine microalgae can be cultivated in photobioreactors for biofuel production. To optimize biomass yield, LED arrays are used to provide precise wavelengths of light.

The dry mass productivity ( $P$ ) of the microalgal culture can be calculated using this equation:

\frac{E}{0.25C}

where:

$E$ is the light energy absorbed by the culture
$C$ is the biomass energy conversion factor

The table below shows the parameters measured for a specific strain of microalgae under LED illumination:

$\text{ / MJ m}^{-3}\text{ d}^{-1}$	$\text{ / MJ kg}^{-1}$
$7.35 \times 10^{-2}$	$24$

Use the equation and the table to calculate the dry mass productivity ( $P$ ) of the microalgae.

Give your answer in standard form and give the units.
