The henry's law constant for co 2 ( g ) in water at 25 ∘ c is 29.4 bar⋅m − 1 . estimate the concentration of dissolved co 2 ( g ) in a carbonated soft drink pressurized with 1.95 bar of co 2 ( g ) .

The concentration of CO₂ in the carbonated soft drink (at 25°C) is 57.3 M

Explanation:

The concentration of a gas (C) in a liquid depends on its partial pressure (P). The higher the partial pressure, the higher its concentration in the liquid. The mathematical expression is known as Henry's law.

C = k . P

where,

k is the Henry's constant

C = (29.4 bar⁻¹ . M) . 1.95 bar = 57.3 M

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
