Suppose a sample of vinegar contains 0.0685 g/mL of acetic acid, which has a molar mass of 60.052 g/mol. How many moles of acetic acid are present in a 19.6 mL solution of the vinegar?

your picture is not part of the scientific method.

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.
