What is the percentage strength of a 1:16 ratio strength solution?

Rationale

The percentage strength of a 1:16 ratio strength solution is 0.63%.

To find the percentage strength of a solution, you divide the amount of solute by the total amount of solution, then multiply by 100. In a 1:16 solution, there is 1 part solute in 16 parts of solution, which gives a percentage of 0.63%.

A (0.53%) YOUR ANSWER

This choice inaccurately calculates the concentration of the solution. The percentage is derived from the ratio of the solute to the total solution volume. A 1:16 ratio results in a higher percentage than 0.53%, indicating a miscalculation.

B (0.63%) CORRECT

This is the correct answer, as it accurately reflects the calculation for a 1:16 solution. The formula used is (1 part solute / 17 total parts) × 100 = 0.63%. This correctly represents the concentration of the solution.

C (5.26%) YOUR ANSWER

This option is far too high for a 1:16 strength solution. A calculation error likely led to this choice, as it does not properly account for the total volume of the solution, which includes both solute and solvent.

D (6.25%) YOUR ANSWER

While this number is closer than others, it still misrepresents the ratio's actual concentration. The calculation should be based on the total of 17 parts (1 solute + 16 solvent), which leads to a much lower percentage than 6.25%.

Conclusion

The percentage strength of a 1:16 ratio solution is calculated to be 0.63%, derived from the appropriate formula considering the total volume of the solution. The other choices do not accurately reflect the ratio's implications, demonstrating the importance of precise calculations in determining solution concentrations. Understanding these calculations is essential in fields like chemistry and pharmacology, where accurate solution strengths are crucial.

What is the percentage strength of a 1:16 ratio strength solution?

The percentage strength of a 1:16 ratio strength solution is 0.63%.
