What happens when a piece of hot metal is dropped in room temperature water. Over time the metal will cool and the water will heat up. Eventually the two objects will have the same temperature. They are then said to be in thermal equilibrium with one another.
The question requires us to use the dilution formula , where and are the stock concentration and volume respectively, then and are the dilute concentration and volume respectively.
a. = 1.5 M KCI, =0.20M KCl, =250ml KCl
b.
To prepare the solution 33.3ml of 1.5M KCl is diluted to a total final volume of 250ml.
