Answer & Explanation:
As an Alka-Seltzer tablet dissolves in water, it liberates carbon dioxide. ... This carbon dioxide gas has mass, but since it is a gas it escapes from the container and diffuses into the atmosphere. The loss of mass from the container is measured directly with the analytical balance.
Random motion of molecules produces a concentration gradient and a net movement of solute as random movement of molecules causes diffusion that causes movement of molecules from high concentration to low concentration . No ATP is required in this process. This causes movement of solute molecules and causes concentration gradient.
