if 500 ml of a 15% solution is diluted to 1500 ml, how would you label the final strength of the solution?
I have no clue what the answers to your problems are but it would be much easier for you if you just copy and pasted everything at one instead of doing every individual question. you don't have to, its just easier. sorry I couldn't help.
This looks suspiciously like exam questions.
I doubt if Cleondra will get any help -- especially since she didn't include her answers.
Would your local pharmacy hire an assistant who cheated her way through school??? I hope not!!
To determine the final strength of the solution after dilution, we need to consider the amount of solute (the substance being dissolved) in the initial and final solutions.
Initially, we have 500 ml of a 15% solution. This means that in 500 ml of the solution, there are 15% solute and 85% solvent (the liquid in which the solute is dissolved).
To calculate the amount of solute in the initial solution, we can use the following formula:
Amount of solute = Volume of solution × Percentage concentration
Substituting the values into the formula:
Amount of solute = 500 ml × 15% = 500 ml × 0.15 = 75 ml
So, the initial solution contains 75 ml of solute.
When we dilute this solution to 1500 ml, the final volume of the solution increases, but the amount of solute remains the same at 75 ml. Therefore, to calculate the final strength of the solution, we need to find the percentage concentration of the solute in the final 1500 ml solution.
Final strength = (Amount of solute / Final volume of solution) × 100
Substituting the values into the formula:
Final strength = (75 ml / 1500 ml) × 100 = 0.05 × 100 = 5%
Therefore, the final strength of the solution after dilution is 5%.
To label the final strength of the solution after dilution, you need to determine the final concentration. The initial solution is 500 ml of a 15% solution, and it is diluted to a total volume of 1500 ml.
To find the final concentration, you can use the formula:
C1V1 = C2V2
Where:
C1 = initial concentration
V1 = initial volume
C2 = final concentration
V2 = final volume
In this case, the initial concentration (C1) is 15% and the initial volume (V1) is 500 ml. The final volume (V2) is given as 1500 ml.
Plugging these values into the formula, we have:
(15%)(500 ml) = C2(1500 ml)
Now, we can solve for C2, the final concentration:
C2 = (15%)(500 ml) / (1500 ml)
C2 = (0.15)(500 ml) / (1500 ml)
C2 = 75 ml / 1500 ml
C2 ≈ 0.05 (or 5%)
Therefore, the final strength of the solution after dilution would be approximately 5%.
