Answer:
424 grams CaCl₂
Explanation:
To find the mass of CaCl₂, you need to (1) calculate the moles (using the molarity ratio) and then (2) convert moles to grams (using the molar mass). The final answer should have 3 sig figs to match the given value with the least amount of sig figs.
(Step 1)
Molarity (M) = moles / volume (L)
1.56 M = moles / 2.451 L
3.82 = moles
(Step 2)
Molar Mass (CaCl₂): 40.078 g/mol + 2(35.453 g/mol)
Molar Mass (CaCl₂): 110.984 g/mol
3.82 moles CaCl₂ 110.984 g
---------------------------- x ------------------- = 424 grams CaCl₂

The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.
<h3>What is the gas law?</h3>
The gas laws can be used to describe the behavior of the ideal gases. It is pertinent to note that the ideal gas law can strictly be applied to gases that are at a high temperature and low pressure.
We can be able to find the temperature when the pressure is equal to zero either be the use of the equation line or by experiment. In that case, we would be able to obtain the point at which the pressure drops to zero.
The significance of the point where the pressure drops to zero is that at that point the gases would completely show ideal behavior.
