Answer:

6. 30 g salt in 100 ml water

7. Volume of benzene (solute) = 25mL  

   Volume of solution = 80mL

8. We divide the mass of the element in 1 mole of the compound by the compound's molar mass and multiply the result by 100.

9. Addition, subtraction, multiplication, and division--have application even in the most advanced mathematical theories.

10. Concentration can be increased by dissolving more solute in a given volume of solution - this increases the mass of the solute. Concentration can be increased by allowing some of the solvent to evaporate - this decreases the volume of the solution.

11. A solution which has only a small amount of solute when compared to the solvent is called dilute solution.

12. Volume percent is defined as: v/v % = [(volume of solute)/(volume of solution)] x 100%

13. A concentrated solution is one that has a relatively large amount of dissolved solute.

14. Yes, because the substances are physically combined, not chemically combined or bonded to each other.

15. The concentration of a solution is a measure of the amount of solute that has been dissolved in a given amount of solvent or solution. A concentrated solution is one that has a relatively large amount of dissolved solute. A dilute solution is one that has a relatively small amount of dissolved solute.

Step-by-step explanation:

7. % volume conc. = volume of solute/volume of solution × 100%  

% volume conc. = 25/80 × 100%  

% volume conc. = 31.25%  

The %concentration by volume of benzene in toluene is therefore 31.25%.
