Answer:
336.0 g
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 <u>we solve for grams of sucrose</u>:
2.4 L ⇒ 2.4 * 1000 = 2400 mL
14 % = mass Sucrose / 2400 mL * 100
mass Sucrose = 336.0 g
Answer:
Mostly Metals, But hydrogen is the only one that isn't.
