Opening a soda bottle illustrates how a decrease in pressure amount of gas that can be dissolved in water.

a. not change

b. decrease

c. increase

The correct answer is Option b.

Explanation:

This solubility of a gas with change in pressure is described by Henry's Law.

This law states that the mass of a gas dissolved in a given volume of the liquid at constant temperature is directly proportional to the pressure of the gas present in equilibrium with the liquid.

Mathematically,

or,

Where, m = mass of the gas dissolved in a unit volume of the solvent

K = Proportionality constant

p = Pressure of the gas in equilibrium with the solvent.

With increase in pressure, the mass of gas dissolved will also increase and vice-versa.

Hence, the correct answer is Option b.

= 3.064 g/L

Using the equation;

PV = nRT , where P is the pressure,. V is the volume, n is the number of moles and T is the temperature and R is the gas constant, 0.08206 L. atm. mol−1.

Number of moles is 1 since one mole has a mass equivalent to the molar mass.

Therefore; We can find the volume and thus get the density.

V = nRT/P

   = (1 × 0.08206 × 498 )/ 0.939

   = 43.52 L

But; density = mass/volume

Therefore;

Density = 133.34 / 43.52

             = 3.064 g/L
