If 125mL of a 0.15M NaOH solution is diluted to 150mL, what will the new molarity of the solution be?

C NaOHsln = 0.125 M

Explanation:

Molarity (M) [=] mol/L

∴ moles NaOH = (0.125 L)(0.15 mol/L) = 0.01875 mol

∴ Vsln = 150 mL = 0.150 L

New Molarity:

⇒ C NaOH = 0.01875 mol/0.150 L

⇒ C NaOH = 0.125 M

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it

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.
