2 mL of heptane plu 2 mL of alpha pinene give 4 mL of solution. Howmany grams per mL are in that mixture? Suppose you diluted 0.25 mLof the 50:50 heptane/alpha-pinene mixture to 5 mL with solvent andmeasured the optical rotation. How many grams per mL in the solution? By what factor would you multiply the value ofαD to get the specific rotation of alpha-pinene?
A gas is confined to a container with a massless piston at the top.A massless wire is attached to the piston. When an external pressure of 2.00 rm atm is applied to the wire, the gas compresses from 5.90 to 2.95 L. When the external pressure is in..
