A student adds 10.00 mL of a 2.0 M nitric acid solution to a 100.00 mL volumetric flask. Next, 50.00 mL of a 0.00500 M solution of KSCN is added by pipet. Deionized water is added to the flask to dilute the solution to the 100.00 mL mark. What is the concentration of the new solution?

0,20M of nitric acid

0,00250M of KSCN

Explanation:

For nitric acid, the dilution is from 10,00mL to 100,00mL. That is a 1/10 dilution. As the initial concentration of nitric acid is 2,0M, the new concentration is: 2,0M× (1/10) = 0,20M of nitric acid

For KSCN the dilution is from 50,00mL to 100,00mL, that is a dilution 1/2. Thus, the new concentration of KSCN is:

0,00500M × (1/2) = 0,00250M of KSCN

I hope it helps!

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
