Hi today we did the lab and the isopropanol density we've calculated was 1.3g/mL
is this possible cuz this number is lyk way too off

The reference I have lists the density of isopropanol as 0.785g/cm^3. This number is approximately the reciprocal of your value of 1.3; perhaps you got a division flipped upside down in your calcualtions? However, I don't know which process you used to determine the molecular weight; it's just a thought.

Isopropanol is a common name for 2-propanol, a colorless, flammable chemical compound with a strong odor. It has the chemical formula C3H8O and is the simplest example of a secondary alcohol, where the alcohol carbon is attached to two other carbons. It is an isomer of propanol. The density is 0.785 g/cm³

You're always bound to make mistakes in lab, and you most likely never will receive the right answer. I would calculate the accuracy of your findings and than discuss what went wrong in your report.
