Explanation:
Boyle's law states that:
"For an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume".
Mathematically:

where
p is the pressure of the gas
V is the volume of the gas
The important condition in order to verify Boyle's law in an experiment is that the temperature of the gas must remain constant. This means that the temperature of the gas during the experiment must be kept constant. This can be achieved, for example, by placing the apparatus containing your gas (for example, a glass tube) inside a thermal bath: for instance, a large amount of water kept at constant temperature. This way, the gas inside the tube will also have the same temperature of the water, which is constant.

Answer:
700 mL of water
Explanation:
This is the perfect example of dilation calculations. Along with this concept we have a formula c = n ( solute ) / V ( solution ). Let us first solve for n by changing this equation to isolate the solute,
n ( KCL ) = 2.4 mol / L * 500 * 10 ^ - 3 L,
n ( KCL ) = 1.2 moles ( KCL )
Knowing the amount of moles of potassium chloride, we have to now identify how much is present in the target solution,
V = 1 .2 moles / ( 1.0 moles / L )
V = 1.2 L = 1200 mL
_______________________________________________________
Vadded = 1200 - 500 = 700 mL
