Answer:

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).

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
