Answer:
1.0 × 10⁻⁵ mol/L
Step-by-step explanation:
The concentration of a gas (C) in a liquid depends on its partial pressure (P), as expressed in Henry's law.
C = k × P
where,
k is the henry's law constant
When the partial pressure of the gas equilibrates at 3.0 × 10⁻⁴ atm, its concentration in the liquid is:
C = k × P
C = 3.4 × 10⁻² mol/L.atm × 3.0 × 10⁻⁴ atm
C = 1.0 × 10⁻⁵ mol/L
