Amount = mass/molar mass
:- mass = Amount × Molar mass
Mass = 16.97g
Answer: Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
Explanation:
You have to find the gram formula mass of C6H6 then do mass (g) = mol x GFM
