Which of the following represents a weight to volume (w/v) percent solution? A) 50 ml of solute in 100 ml of solution. B) 10 g of solute in 200 ml of solution. C) 25 g of solute in... Which of the following represents a weight to volume (w/v) percent solution? A) 50 ml of solute in 100 ml of solution. B) 10 g of solute in 200 ml of solution. C) 25 g of solute in 100 g of solution. D) 100 g of solute in 100 ml of solution.
Understand the Problem
The question is asking which option correctly defines a weight to volume (w/v) percent solution. A w/v percent solution typically expresses the mass of solute in grams per 100 ml of solution, and we need to identify which of the provided options fits this definition.
Answer
B) 10 g of solute in 200 ml of solution.
The final answer is B) 10 g of solute in 200 ml of solution.
Answer for screen readers
The final answer is B) 10 g of solute in 200 ml of solution.
More Information
A weight/volume (w/v) percent solution refers to the grams of solute in a 100 mL of solution. Option B describes grams per volume suitable for conversion to w/v percent.
Tips
A common mistake is to choose options with volumes not equal to 100 mL for w/v percent calculations.
