On a clear day at sea level, with a temperature of 25°C, the partial pressure of N₂ in air is 0.78 atm and the concentration of nitrogen in water is 5.3 × 10^-4 M. When the partial pressure of N₂ is __________ atm, the concentration in water is 1.1 × 10^-³ M. A)0.63 B)0.78 C)1.0 D)2.1 E)1.6

Question

According to Henry's Law, the concentration of a gas in a liquid is directly proportional to the partial pressure of the gas above the liquid. Doubling the concentration from 5.3 × 10^-4 M to 1.1 × 10^-3 M requires doubling the partial pressure from 0.78 atm to 1.6 atm.
