If a cell culture has 3 x 105 cells per ml , and the culture flasks hold 75 ml of culture each and you have 12 flasks, how many
natta225 [31]

There are 27 x 10⁷ cells in total for the given conditions of cell culture.

Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.

Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-

75 x 12 = 900 ml

Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-

900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells
