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

I believe the correct answer would be that b<span>oiling points and melting points are similar because they both involve the change in a state of a material, but they are different because boiling point involves a change from a liquid to a gas and melting point involves a change from a solid to a liquid. Boiling and melting are phase changes that can happen to a substance however they differ in the process that happens.</span>
Answer:oxidation number H = +1
oxidation number O = -2
let x = oxidation number Cl
in HClO3
+1 + x -6 =0
x = +5
