2. A solution containing 320.4 g of Mg(NO3)2 per liter has a density of 1.114 g/mL. The molarity of the solution is:

As you move from right to left on the periodic table the atomic radius fill in the blank

Calculate the expected ph values of the buffer systems from the experiments (a, b,c, d), using the henderson- hasselbalch equation, ph-pka+log[a-]/[ha]. use for pka values carbonic acid= 6.37, and acetic acid= 4.75.

Particles vibrate in a rigid structure and do not move relative to their neighbors.
