Kilogram The volume of helium in a blimp is 6.28 x 10°milliliters. The density of helium in the blimp is 0.1786 meter3 Find the mass of the helium in
the blimp. (Hint: 1.000 L = 1 cubic meter.)

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.
