The image shows that Flixonase contains fluticasone propionate at a concentration of 0.05% w/w. This means 0.05 grams of fluticasone propionate are present in 100 grams of the solution. The problem asks about this concentration. No actual calculation is needed, just an explanation of what "0.05% w/w" means.

1. Problem Description

The image shows that Flixonase contains fluticasone propionate at a concentration of 0.05% w/w. This means 0.05 grams of fluticasone propionate are present in 100 grams of the solution. The problem asks about this concentration. No actual calculation is needed, just an explanation of what "0.05% w/w" means.

2. Solution Steps

The notation "% w/w" stands for "percent weight by weight". This means the concentration is expressed as the weight of the solute (fluticasone propionate) divided by the weight of the solution, multiplied by 100%.

$concentration = (weight \ of \ solute / weight \ of \ solution) * 100\%$

In this case, the concentration is 0.05% w/w, which means for every 100 grams of the nasal spray, there are 0.05 grams of fluticasone propionate.

3. Final Answer

0. 05% w/w means that there are 0.05 grams of fluticasone propionate for every 100 grams of the Flixonase nasal spray.
