Density = mass / volume. These can be many different units, but in the metric (SI) system for liquids and solids mass is usually measured in grams and volume in cubic centimeters, so density becomes grams / cm3.

percent error = [(experimental value - actual value)/(actual value)] x 100 so in this case: % error = [(68.7-63.50)/(63.5]x100
