Prepare 20mL 27%(wt/vol) PEG in water if you are given solid PEG (avg. MW 8000g/mol) and 30mL 20% PEG?

September 23rd, 2008 · No Comments

Also, you can’t add any pure water!

(By the way, PEG stands for polyethylene glycol.)

Please help me understand how to figure out this problem. Detailed explanations are more than welcome! Thank you.
