Why do we need to use six separate pipets for known solutions and a different six separate pipets for the unknown solutions, and having them all be dedicated to it's own solutions?
In a typical cold pack (used for sports injuries), a salt such as ammonium nitrate is kept in a separate pouch from a bag of water. When the pouch is punctured, the salt readily dissolves in the water, and the pack becomes noticeably cooler to the touch (temperature decreases from room temp to about 5 oC). Based around le Charlier principle conclude the signs for ΔHº, ΔSº, and ΔGº for the solvation of ammonium nitrate in water.

A common practice in cooing is the addition of salt to boiling water. The boiling point of elevation is described by the equation, which is similar to freezing point depression equation but uses a different constant. imagine that your friend tells you that this is done in order to raise the temperature of the boiling water. If 1.50 kg (1.50L) of water is boiling at 100 degrees celsius how much NaCl (molar mass= 58.44g/mole) would need to be added to the water to increase the boiling point by 1 degree Celsius? Does your friend's explanation make sense?
