Question

A student intended to make a salt solution with a concentration of 10.0 grams of solute per liter of solution. When the student's solution was analyzed, it was found to contain 8.90 grams of solute per liter of solution. What was the percent error in the concentration of the solution?

Answer 1

(1-(actual value / expected value)) x 100% = % error 

(1 - (8.90g/L / 10.0g/L)) x 100% = 11% error is the percentage error in concenrtation of solution
