Weighing by Difference

Weighing by Difference. Why Weigh by Difference?. The amounts of solid samples weighed in this course are generally small . I.e., often 500 mg or less. Analytical balances can weigh objects with a precision of about 0.2 mg . For a 500 mg sample, this is 100 x 0.2 / 500 = 0.04 %
