Answer:
.234 M
Explanation:
Molarity, or concentration, of a substance is simply found by dividing the amount of that substance in moles by its volume. Here, we are given the mass (in grams) of Kool-Aid, so we need to convert that to moles. To do this, we simply need the chemical formula of Kool-Aid, which I have found to be C12H22O11. The molar mass of C12H22O11, using the periodic table, is 342.296 g. Next, take this molar mass and divide the given mass of Kool-Aid by it. You then get about .234 mol Kool-Aid.
Lastly, divide this by the volume of 1.0 L. You get .234 M as your final molarity.
