The molarity of pure water (density of water=`1g ml^-1`)

Density of water is

Molality of pure water is……………… .

The volume of 500 g sealed packed in 350cm^3 . Will the packet float or sink in water of the density of water is 1gcm^-3 ? What will the mass of the water displaced by his packet?

An antifreeze solution is prepared fro, 222.6g of ethylene glycol, C_2H_4(OH)_2 and 200g of water. Calculate the molality of the solution . If the density of the solution is 1.072g mL^-1 , then what shall be the molarity of the solution?

36 mL of pure water takes 100 sec to evaporate from a vessel when a heater of 806 watt is used. The DeltaH_("vaporisation") of H_(2)O is (density of water =1g//c c)

Commercially available HCl contains 38% HCl by mass. Calculate molarity of solution if the density is 1.19 g/ml.
