What concentration of a solution made by dissolving 4.17g of KBr in water to make the final volume of 500ml?
If you could, please explain how to solve this. I'm dying here trying to solve it. Help would be greatly appericated.

MV = grams / molar mass
(x) (0.500 L) = 4.17 g / 119.002 g/mol
x = 0.070 mol/L (two sig figs in the answer seems like a reasonable compromise. Check with your teacher on this point.)
Saw this from 11 months ago:
"I guess what I'm trying to ask is, Is it normal to feel this bad when you don't work out? Why does it happen? "
When you work out, your body generates endorphins. These chemicals have structures similar to drugs like morphine, which make you high. (I remember my mom on her deathbed. She was higher than a kite on morphine and it didn't bother me one bit. She went peacefully in her sleep about 2 days later.) Hope you're back to some good work outs.
