Into a 1.00 liter flask are placed 0.820 moles of NO and 0.223 moles of N2 and O2. What are the concentrations of NO, N2, and O2 at equilibrium? For the molarity for each, I got this: NO= .027 M N2= .0079 M O2= .0069 M balanced equation: 2NO(g) <-> N2(g) + O2 How do I ...

chemistry,
in analyzing household bleach. I have a flask that contains 10.00 mL diluted bleach + 0.4g KI + 20 mL distilled water and 20 drops of 2M HCl. To that I titrated 30.60 mL Na2S2O3 and I need to calculate the number of moles of NaOCl reacted. This is what I was thinking.. ...

A aqueous solution of acetic acid with a density of 1.25 g/ml is 30.0% by mass HC2h3O2 (MM=60.0) Compute the molarity of this solution. I figured out that if you divide 30.0 by the molar mass 60.0g which gives you .5 mol. I cannot seem to figure out what i change 1.25 g/ml ...
