Answer to Question #337419 in Biochemistry for sana

Question

Assume the linear fit of the standard curve using DNSA absorbance at 540nm versus glucose concentration in M is y=0.002x + 0.003. Calculate the concentration of an unknown solution of glucose with DNSA absorbance at 540nm of 0.17.

Answer 1

Instead of y we put 0,17 and just solve linear equation. 0,17=0,002x+0,003

0,167=0,002x

X=83,5M- concentration of glucose
