Answer 2

Answer:

1%

Diffusion and osmosis

Explanation:

a)  % by weight =Mass of Solute /Mass of Solution x100

b)   CO^  2   is gas so, it moves in and out of the cell by diffusion. Diffusion is a process in which the molecules intermingle due to their kinetic energy and the movement of molecules is from higher concentration to lower concentration.

H  ^2  O moves in and out of the cell by osmosis, in which the water molecules move from lower solute concentration to higher solute concentration through the cell membrane.
