Question

Calculate the concentration of dissolved gas in water at 25°C if partial pressure of gas at same temperature is 0.15 atm. [KH = 0.15 mol dm^-3 atm^-1]

पर्याय

• 0.0261 M

• 0.0182 M

• 0.0293 М

• 0.0225 M

Answer 1

0.0225 M

Explanation:

Concentration of dissolved gas

= K_H × P

= 0.15 mol dm^-3 atm^-1 × 0.15 atm

= 0.0225 mol dm^-3 = 0.0225 M
