Hello DrBob222 Regarding the answer you gave me thank you very much. However when you expand the denominator, I don't get -0.14 but I get -0.28. I get that because when I first expand I get 0.0049 - 0.14x - 0.14x + 4x^2. So when I simplify that I get -0.2...

So all I have to do now is cross multiply and solve for x right? Also when that happens, how do I factor the x^3? What do I do?

My Question is: Commercial vinegar usually has a concentration of 5%, per volume. Calculate the [H3O+], if the density of acetic acid is 1.051 g/mL. What I did was: mass = V * density mass = 0.05 * 1.051 = 0.05 g moles = grams/molar mass = 0.05/60.05 = 8....

Hello There How I did a) was that I know that the equation for the reaction quotient was products/reactants. In this situation however, since I already have 0 moles of both products it would immediately mean that any number divided by 0 is 0. For b), the...
