In the lab, you dissolve 179 g of MgCl2 into 1.00 L of water. Find the freezing point of the solution. {Normal freezing point is 0oC and Kf = oC kg/mol}

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.

Calculate the mass of silver needed to react with chlorine to produce 126g if silver chloride?

What volume would 2.25 moles of ne has occupy at stp?
