Potassium 2:5 Chloride solution 30ml. How many milliliters of a potassium chloride 3:5 solution do you need to prepare the order?
I asked earlier what you meant by a 2:5 and 3:5 solution and you didn't answer. I asked because there are several meanings to this. In my book a 2:5 solution is 40%(200/5) and a 3:5 solution is 60% (300/5).
So I use
c1v1 = c2v2
40*30 = 60*v2
v2 = 20
That is, add 20 mL of the 3:5 to a flask and add sufficient water to make 30 mL (10 mL) H2O to end up with 30 mL of 2:5 solution.
so in other words DrBob, you dont know either
To find out how many milliliters of a potassium chloride 3:5 solution is needed to prepare the order, we can use a proportion.
Let's break down the information we have:
- Potassium 2:5 Chloride solution: This means the solution has a potassium chloride ratio of 2:5.
- Order quantity: 30 ml
Now, let's set up the proportion to solve for the required volume of the potassium chloride 3:5 solution:
(2:5) / (3:5) = (30 ml) / (x ml)
To simplify the proportion, we cross-multiply:
(2/3) * x = (5/5) * 30
Simplifying further:
2x/3 = 30
Multiply both sides of the equation by 3 to isolate x:
2x = 90
Divide both sides of the equation by 2 to solve for x:
x = 45
Therefore, you will need 45 milliliters of a potassium chloride 3:5 solution to prepare the order.
