I am solving a problem for my organic chem lab and here are the values given
160 mg of an organic compound
dissolved in 8 mL of water
the solution place in a 10 cm polarimeter
Value obtained is +26.6 degrees. Calculate the specific rotation for the compound.
HERE IS WHAT I DID:
c = mass/volume = 0.160 g/8 mL = 0.020 g/mL
l = 10 cm = 1 dm
[α] = (+ 26.6 °)/(0.020 g/mL ×1 dm)
[α] = + 1330 °
so my final answer is 1330 degrees, is that even normal? Could 1330 also be stated as +250?
