At 25.0 °C the Henry's Law constant for sulfur hexafluoride (SP) gas in water is 2.4x 10 M/atm Calculate the mass in grams of SF
Dmitry_Shevchenko [17]

Complete Question

The complete question is shown on the first uploaded image

Answer:

The mass is m =  0.0349 \ g

Explanation:

From the question we are told that

   The Henry's Law constant is  k = 2.4 *10^{10} M/atm

   The volume of water is V = 525 \ ml = 0.525 \ L

   The partial pressure is  P =  1.90 \ atm

   The temperature is T  = 25 ^oC

Henry's  law is mathematically represented as

       C  = P * k

Where C is  the concentration of sulfur hexafluoride(SP)

substituting value

        C = 1.90 * 2.4*10^{-4}

        C = 4.56*10^{-4} \ M

The number of moles of  SP is mathematically represented as

        n = C * V

substituting value

       n =  0.525 * 4.56*10^{-4}

       n =  2.39 *10^{-4} \ moles

The mass of SP that dissolved is

          m = n * Z

Where Z is the molar mass of SP which has a constant value of

           Z = 146 g/mole

So

         m =  2.394*10^{-4} * 146

         m =  0.0349 \ g
