At what temperature, the density of water is maximum?

The density of O_(2)"(g)" is maximum at :

Using the equation of state PV = nRT, show that at given temperature density of gas is directly proportional to gas pressure.

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?

Answer the following What is the temperature of the triple point of water on an absolute scalw whose unit interval size is equal to that of the Fahrenheit scale?

Assertion: Increasing pressure on water decreases its freezing point Reason: Density of water is maximum at 273K.

What is the highest value of density of water?

Hundred gram of Al(HNO_3)_3 (molar mass 213 gmol^-1 ) is dissolved in 1 L of water at 20^@C . The density of water at this temperature is 0.9983 gcm^-3 and the density of resulting solution is 0.9990 gcm^-3 . Calculate the molarity and molality of this solution.
