- How do you solve #v=sqrt (a^2)-x^2# for #x#? - Socratic
x=+-sqrt(a-v) v=sqrt(a^2)-x^2 Apply square root rule sqrt(b^2)=b v=a-x^2 Add x^2 to both sides v+x^2=a Subtract v from both sides x^2=a-v Take the square root of both sides sqrt(x^2)=+-sqrt(a-v) x=+-sqrt(a-v)

- Question #9c6af - Socratic
"3 2 mol kg"^(-1) In order to be able to calculate the molality of the solution, you need to know the number of moles of solute present for every "1 kg" = 10^3 "g" of solvent In your case, you know that this solution is "16% m m" urea, which implies that you get "16 g" of urea, the solute, for every "100 g" of solution If you take a "100-g" sample of this solution, you can say that it
