If the calibration curve is plotted with absorbance on the y-axis vs the concentration of P (ppm P) on the x-axis. If the equation of the calibration curve is
A=mc=0.1683c
and
A=εbc
therefore m=εb and rearrange and solve for ε.
If the cell path length b is 2.00 cm, calculate the absorptivity in units of 1/(mol/L P·cm) or L ·mol P-1 · cm-1.
Report your answer to the nearest whole number (i.e., no decimal places).
如果你算得出来这道题,而且算对了_(:з」∠)_ 那我把题目发上来

我关注你很久了，起初只是觉得你的ID好听，声音也是我喜欢的类型，后来经常看到你，很想认识你，我却一直不好意思说话，也不知道说什么，所以我假装是在水经验，其实我是想和你借机表白。
