Asolution is made with 2 g of salt (nacl) and 150 g of water (h2o).
which option describes the components of the solution?
a. the salt is the solute, and the water is the solvent.
b. the salt and the water are both solvents.
c. the salt is the solvent, and the water is the solute.
d. the salt and the water are both solutes.

A.

Explanation:

The salt dissolves in the water so it is the solute and the water is the solvent.

c (diamond),

sio2 (quartz)

answer : (a) volume of the gas = 8.67 ×   l

                (b) second virial coefficient b = -1.21226 l/mole

solution :   given,     t = 300k

                                p = 20atm

                                z = 0.86

                                n = 8.2 mmoles = 8.2 × moles

                                r =   0.082 l atm/k/mol

        find,     (a) volume of gas   and (b) second virial coefficient b at 300k.

formula used :            

                          and            

(a)            

                    = \times 0.082\times 300}{20}[/tex]

                    = 8.67 ×   l

(b)      

                    = (0.00867-1) × 8.659

                    = - 8.5839 l/mole
