You have 627 ml of 5.04 M HCl. Using a volumetric pipet, you take 229 ml of that solution and dilute it to 921 ml in a volumetric flask. Now you take 100.00 ml of that solution and dilute it to 192 ml in a volumetric flask. What is the concentration of hydrochloric acid in the final solution? Enter your answer numerically in units of M to three significant figures.

Determine which intermolecular forces are the dominant (strongest) forces for a pure sample of each of the following molecules by placing the molecules into the correct bins. drag the appropriate molecular formula to their respective bins.
