The Henry's law constant for helium gas in water at 30 °C is 3.70 × 10^-⁴M/atm. When the partial pressure of helium above a sample of water is 0.650 atm, the concentration of helium in the water is M A) 1.76 × 10³ B) 2.41 × 10^-⁴ C) 5.69 × 10^-⁴ D) 3.70 × 10^-⁴ E) 1.30

Question

Quizplus · Accepted Answer

The concentration of helium in water can be calculated using Henry's law: C = kP, where C is the concentration, k is the Henry's law constant, and P is the partial pressure. Substituting the given values: C = (3.70 × 10^-4 M/atm) × (0.650 atm) = 2.41 × 10^-4 M.
