Bromine and Iodine are both totally soluble in mineral oil because these substances are all made up of non-polar molecules. And because water is a polar molecule, Bromine and Iodine is not soluble in it.

Non polar solvents contain bonds that have similar electronegativity, an example of this is carbon and hydrogen such as gasoline. Some other examples are pentane, hexane, benzene and toluene.

The average mass of a kernel of popcorn is 0.125 g if one pound equals 16 oz, and 1 oz equals 28.3 g then how many kernels of po
Nikitich [7]
I won't give the answer, but here's the process: You have the weight of the object (0.500 lbs), and you want to convert that into the number of kernels. You are given the fact that 1 pound = 16 oz, and 1 oz=28.3 grams. So it should be apparent that you need to convert pounds to ounces first and then convert ounces to grams. Now that you the grams, you can easily figure out how many kernels there are because .125 grams equals the weight of one kernel.

An iron ore was found to contain 92.0% pyrite (fool's gold). Pyrite has the formula FeS2and is 46.5% iron. How many grams of iro
Liula [17]
Firstly calculate the grams in the last 8 percent before moving onto the pyrite section.
50.8x0.08=4.064g
We know that iron ore in this case has 92 percent pyrite which contains 46.5 percent iron so we do 50.8x0.92=46.736g from this we need to find 46.5 percent of the iron content in the 92 percent pyrite section then add this answer to the 8 percent of iron ore we found at the start.46.736x0.465=21.73224g
21.73224g+4.064=25.79624g of iron ore 25.8g(3sf)
