Thank you very much! That helps a lot.

Yeah, im sorry, i made a mistake. The actual concentration is 99.7% v-v, and the density is 0.786 g/cm3.

Hi there!

I'm having trouble calculating the molar concentration of 70% isopropanol (2-propanol). Said 70% is by weight. I'd really appreciate some help since i don't know how to calculate this.
