A molecule of sucrose has a molecular weight of 342 daltons. How many grams of sucrose would be required to make one liter of a 2.5 Molar solution of sucrose?
What will be an ideal response?
805 grams (per liter). This is calculated by multiplying the amount of sucrose in one liter of a 1 molar solution (342 grams) times the molar concentration (2.5). 342 × 2.5 = 805 grams
