When a 10 mL graduated cylinder is filled to the 10 mL mark, the mass of the water was measured to be 10.085 g at 20ºC. If the density of water is taken to be 0.9975 g/mL at 20ºC, what is the percent error for the 10 mL of water.

To calculate percent errorsubtract the accepted value from the experimental value. Take the absolute value of step 1. Divide that answer by the accepted value. Multiply that answer by 100

so% error = [| (10.085 g / 10 ml) - 0.9975| / 0.9975] x 100

% error = 1.1 %
