1 gal ----------- 3785.41 cm³
2.9 gal ---------- ??
2.9 x 3785.41 / 1 => 10977.689 cm³
Answer: 66.83g
Explanation: (200.59 g/mole = Hg)
0.33 moles = 66.83g
<span>Flubber would have to be a liquid, but it has characteristics which are impossible under the known laws of physics. I heard my teacher say that once</span>
You can separate a mixture of salt and sand by...
First combing the mixture with water and mix thoroughly until the salt dissolves..
Then you could let the sand settle at the bottom of the salt water, so you can strain salt water to separate the sand from salt water...
To get salt... you would heat up the water to let it evaporate. When all the water is evaporated, the salt will be left behind
The solubility product of a substance us calculated by the product of the concentration of the dissociated ions in the solution raise to the stoichiometric coefficient of the ions. Therefore, we need the dissociation reaction. For this, it will have the reaction:
PbI2 = Pb^2+ + 2I-
We solve as follows:
Ksp = [Pb2+][I-]^2 = <span>1.4 x 10-8
</span><span>1.4 x 10-8 = x(2x)^2
</span><span>1.4 x 10-8 = 4x^3
x = 1.5x10^-3 M
The molar solubility would be </span>1.5x10^-3 M.
