The Henry's law constant for helium gas in water at 30°C is 0.000370 M/atm. When the partial pressure of helium above a sample is 0.400 atm, what is the concentration of helium in the water?

What volume of water, in mL, is needed to dissolve 6.3×10^1 mg of carbon monoxide gas (28.0 g/mol) when the partial pressure of carbon monoxide above the water is 3.8 atm at 25 °C? The Henry's constant for carbon monoxide gas in water at 25 °C is 9.5×10^-1 M/atm.

The Henry's law constant at 25 °C for CO₂ in water is 0.035 M/atm. What is the solubility of CO₂, in molarity units, in 1.0 L of water when the partial pressure of CO₂ is 2.3 atm?
