Question

How many grams of sucrose would you add to water to make a total of 2.4 L of 14 % solution (mass per volume)? Make your answer's precision to one decimal place

Answer 1

336.0 g

Step-by-step explanation:

The definition of concentration by percentage in mass per volume can be expressed as:

% m/v = mass Sucrose (in g) / Volume of Solution (in mL) * 100

The problem gives us the concentration and the volume, so we solve for grams of sucrose:

2.4 L ⇒ 2.4 * 1000 = 2400 mL

14 % = mass Sucrose / 2400 mL * 100

mass Sucrose = 336.0 g
