Question

a solution is 6% (w/v). which of the following is the ratio strength (w/v) of the solution? choose an answer 1 15 ml 2 237 ml 3 0.02% 4 1:16.7

Explanation:

Step1: Convert percentage to ratio

A 6% (w/v) solution means 6 g of solute in 100 ml of solution. The ratio strength is expressed as 1:x. We set up the proportion $\frac{6}{100}=\frac{1}{x}$.

Step2: Solve for x

Cross - multiply: $6x = 100$. Then $x=\frac{100}{6}\approx16.7$. So the ratio strength is 1:16.7.

Answer:

1. 1:16.7
