Question

A different flask of cultured cells contains 7 x 105 cells in 50 ml of medium. What is the concentration of cells (per ml) (0.5pts)

Answer 1

1.4 x
`10^(4)` cells per ml

Step-by-step explanation:

If there are 7 x
`10^(5)` cells in 50 ml of medium, the concentration of cells in 1 ml of medium can be calculated such that;

7 x
`10^(5)` cells is present in 50 ml

x cells is present in 1 ml

Cross multiply, we have

50x = 7 x
`10^(5)` x 1

x = 7 x
`10^(5)`/50

x = 1.4 x
`10^(4)`.

The concentration of cells per ml is 1.4 x
`10^(4)`.

Answer 2

To find the average number of cell cultured per area, you have to divide the total cell count with the total area. The cultured cells contains 7 x 10^5 cells count in 50 ml of medium area. The number would be: 7 x 10^5 cells / 50ml= 0.14x 10^5 cells /ml= 1.4 x 10^4 cells/ml
