A 0.21 m3 drum contains 100L of a mixture ofseveral degreasing solvents in water. The concentraton oftrichloroethylen in the headspace( gas phase) above the water wasmeasured to be 0.00301 atm. The Henry's constant fortrichloroethylene is 0.00985atm. m3.mol-1 at25o. What is the concentration of tricholoroethylene inthe water in units of molarity? ( assume that the temperature ofthe solution is 25o)

The concentration is 6.42×10^-4 M

Explanation:

Number of moles trichloroethylene = pressure × volume/Henry's constant = 0.00301×0.21/0.00985 = 0.0642 mol

Volume of mixture = 100 L

Concentration of trichloroethylene = number of moles of trichloroethylene/volume of solution = 0.0642/100 = 6.42×10^-4 M

d.) the average kinetic energy of the gas particles is greater in container b because its particles move faster.

in cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level. a contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes.
