Calcipotriene (SORILUX) foam, 0.005% w/w, is supplied in containers holding 60 g of product. (1) is the number of milligrams of calcipotriene per container. Round answer to the nearest whole number. Do not include units.

Step 1 is to express the percentage concentration as a decimal or ratio 0.005% = 0.005 ÷ 100 Result at this step = 0.00005 Step 2 is to calculate the weight of the active ingredient in grams Weight (g) = Total weight × Concentration 60 × 0.00005 = 0.003 Result at this step = 0.003 g Step 3 is to convert grams (g) to milligrams (mg) mg = 0.003 × 1000 0.003 × 1000 = 3 Result at this step = 3 Step 4 is to round to the nearest whole number 3 = 3 Answer: 3
