Question 6

A marine biologist is monitoring the population growth of a microalgae species, Chlorella, in a photobioreactor. On day 5, the concentration of microalgae cells in the culture was determined to satisfy the equation

log⁡10(C)=5.84 \log_{10}(C) = 5.84 log10​(C)=5.84

where C C\,C is the concentration of cells per cm3\text{cm}^3cm3.

Calculate the total number of microalgae cells that would be present in a 35 cm3 sample of this culture on day 5.

Provide your answer in standard form to three significant figures.
