Question

1) A solution is made by dissolving 6.35g of glucose (C6H1206)in 25.0 mL of water. The density of water is 1.00 g/mL. Calculatethe molality of the solution

2) A solution contains 5.0g of toluene (C7H8) and 255g ofbenzene and has a density of 0.876 g/mL. Calculate the molarity ofthe solution

3) A solution is made containing 7.5g CH3OH in 275g H20. Assumethe density of water as 1.00 g/mL

A) calculate the mole fraction of CH3OH

B) The mass percent of CH3OH

C) The molality of CH3OH
