Convert the concentration of CoCl2 from 22.0 mg/mL into molarity.
I figured it out. No fraction can appear under a radical.
Thank you! I tried to solve it like this: x^2 + 2y^2 = 8 ( x^2 - y^2 = 1 )2 x^2 + 2y^2 = 8 2x^2 - 2y^2 = 2 3x^2 = 10 x^2 = 10/3 x = ±√(10/3) Any idea as to why my textbook would say that the solution is ±√(30/3)?
Solve the system by substitution or elimination. x^2 + 2y^2 = 8 x^2 - y^2 = 1
