Question 59

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

A 1:16 ratio means that there is 1 part of solute for every 16 parts of solution. To find the percentage strength, you can use the formula: (1 / (1 + 16)) * 100, which gives approximately 0.63%.

A) 0.53%

This option is incorrect because it does not align with the calculation for a 1:16 ratio strength solution. The percentage strength calculated from the ratio yields a value higher than 0.53%.

B) 0.63%

This option is correct as it accurately represents the percentage strength of a 1:16 ratio strength solution. The calculation confirms that this is the appropriate value when considering the dilution of the solution.

C) 5.26%

This option is incorrect because it suggests a much higher concentration than what is represented by a 1:16 ratio. The correct calculation does not support this level of strength.

D) 6.25%

This option is also incorrect as it implies an even greater concentration than option C. The mathematical interpretation of a 1:16 ratio does not yield this percentage, which is too high for the given dilution.

Conclusion

The correct answer, 0.63%, accurately reflects the percentage strength of a 1:16 ratio solution based on the appropriate calculation. All other options fail to represent the correct dilution and concentration, validating that B is the definitive answer.
