    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
