Can anyone can help me with 19 and 20 with process

19.

a. 82.98 g/mol

b. 76.139 g/mol

c. 97.94 g/mol

d. 46.07 g/mol

e. 82.07 g/mol

f. 98.079 g/mol

20.

a. 336.24 g/mol

b. 120.366 g/mol

c. 278.1 g/mol

d. 187.56 g/mol

e. 260.5 g/mol

f.

Explanation:

19. Add up each individual atomic mass of each element. You will find this in the bottom of the element's box on the periodic table.

20. Be familiar with transforming names into compounds. After, do the same thing you did in problem 19.

- Hope that helped! Please let me know if you would like a more in-depth explanation.

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.
