How much sucrose is needed to make 100 mL of syrup?

• A. 75 g
• B. 85 g
• C. 100 g
• D. 90 g

Answer: (B)

Syrups are typically prepared as a sugar solution with a defined weight/volume concentration. For a standard sugar syrup, the concentration is 85% w/v, meaning 85 grams of sucrose dissolved in enough water to make 100 milliliters of solution. So to obtain 100 mL of syrup, you would use 85 g of sucrose and add water until the total volume reaches 100 mL. Heat may help dissolve the sugar, but the final volume must be 100 mL. The other amounts would yield solutions with different sugar concentrations, not the standard syrup.
