Question 4

A scientist recorded the population growth of a bacterial culture in a closed flask. On day 2, the concentration of bacterial cells in the culture was determined to be log⁡10(C)=6.25\log_{10}(C) = 6.25log10​(C)=6.25 cells per cm3\text{cm}^3cm3, where CCC is the concentration of cells.

Calculate the total number of bacterial cells that would be present in a 50 cm350\text{ cm}^350 cm3 sample of this culture on day 2.

Provide your answer in standard form to two significant figures.
