Answer
70.1 x 106 cells/mL or 7.0 x 107 cells/mL
Solution
- Equation for standard line: y = 226.21x
- The absorbance (which is x): 0.31
- Set up the equation: y = (226.21) x (0.31)
- Calculate y: 70.125
- Recall that the graph axis indicates y is x 106, so the final answer is: 70.1 x 106 cells/mL or 7.0 x 107 cells/mL
