If I have 340 mL of a 0.5 M NaBr solution, what will the concentration be if I add 560 mL more water to it?

The correct answer is "0.31 M".

Explanation:

Given,

Volume,

Molarity,

Let the M₂ be "x".

By using the dilution formula, we get

⇒

then,

⇒

⇒          

⇒            

⇒                

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.

58750.08068 is the answer i think
