Which of the following situations could be represented with the given system of equations? 0.1x+0.6y=0.4(5) x+y=5 A. Eunice needs to combine solutions of 0.1M HCl and 0.4M HCl to produce 5L of 0.6M hydrochloric acid (HCl). B. Eunice needs to combine solutions of 0.1M HCl and 0.6M HCl to produce 5L of 0.4M hydrochloric acid (HCl). C. Eunice needs to combine solutions of 0.4M HCl and 0.6M HCl to produce 5L of 0.1M hydrochloric acid (HCl). D. Eunice needs to combine solutions of 0.1M HCl and 0.6M HCl to produce 4L of 0.5M hydrochloric acid (HCl).

Answer :

mathmate
In the equations, the molarity is given as coefficients, x and y are volumes of HCl of different concentrations.  Therefore on the right hand side, molarity is 0.4, volume is 5 L.
The correct answer has a product of 0.4M and 5L.
