Does increasing or decreasing volume change the moles in a solution, or does that just affect the concentration? If I have 0.035711 moles in 100mL and I'm asked how many moles in 5mL...

Ralph Chase plans to sell a piece of property for $180000. He wants the money to be paid off in two waysminus−a short-term note at 12% interest and a long-term note at 9% interest. Find the amount...

Determine the molarity of a solution of concentrated nitric acid. Concentrated nitric acid is 70% by mass HNO3. The density of concentrated nitric acid is 1.42 g/ml

Although I understand Chemistry and have been doing well in the class, I just do not understand this problem. Thank you for any help!

Could anyone help me with this question? Thanks! Suppose you have a solution that contains 100 μg/mL of a substance in 500 μL. You wish to dilute this so that you have 50 μg/mL in 1...

Sulphuric acid is sold in standard stock solutions of concentration 14.5 M. A teacher needs to prepare 175 ml of 2.3 M solution of sulphuric acid.

if the original concentration of alminium hydroxide is 7.5•10^-4 mol/L

I was playing around with tan(4*arctan(x))=2 and noticed x^2-x-1 and x^4-5*x^2+5 were in the solutions. It just seemed strange to me. Do identities work on these? Why is it adding/subtracting...
