Volume of benzene (solute) = 25mL

Volume of solution = 80mL

% 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%.

A solution is made using 161.1 g of toluene (MM = 92.13 g/mol) and 80.0 g of benzene (MM = 78.11 g/mol). What is the molality of the toluene in the solution?

80/78.11=1.024mol= 1.024/0.1611=6.36mol/Kg

What is the molar concertation of 10g of salt (NaCl) in 100 mL of water?

Molar concentration =(mass/molar mass) ×(1000/volume in mL) Molar mass of NaCl = 23+35.5= 58.5g/molMolar concentration = (10/58.5)×(1000/100)Molar concentration = 1.709M
