In Chemistry the primary way is: Molarity = Some helpful equations: MV = It is also a good idea to use millimoles. MV= millimoles (When the volume unit is in mL) Examples: Calculate the molarity of a solution prepared by dissolving 1.56-g of gaseous HCl into 26.8mL. Typical blood serum is about 0.14 M NaCl. What volume of blood contains 1.00mg ...

Molality is greater than molarity because the volume increases when the solute dissolves in water so now the volume of the solution is greater than the mass of the water. If there is very little solute (dilute solution) then it is a good assumption that the volume does not change and molarity equals molality.

There are lots and lots of examples of surface tension. Dishwashing detergent is a good surfactant. 3) Why is ice less dense than water? The hydrogen bonding in ice makes the structure more “open” than in liquid water. The extra spaces between molecules makes solid ice less dense than liquid water, so it …
