What mass of the following chemicals is needed to make the solutions indicated?

Answer:

271.6g

Explanation:

The mass of the chemicals need to make the needed solution can be derived by obtaining the number of moles first.

Given parameters:

Volume of solution  = 1L

Molarity of HgCl₂  = 1M

    number of moles of HgCl₂  = molarity of solution x volume

                                                   =   1 x 1

                                                    = 1 mole

From;

           Mass of a substance  = number of moles x molar mass;

  we can find mass;

          Molar mass of HgCl₂  = 200.6 + 2(35.5)  = 271.6g/mol

       Mass of the substance  = 1 x 271.6  = 271.6g

What would happen if evaporation does not take place in nature​

Plants do not receive natural water and die. And there would be no rivers or lakes because their water comes from evaporation via rain or snow.
