1. The problem statement, all variables and given/known data What is a more precise way of finding the total mass? Weighing 5 individual quarters or weighing them all together? 2. Relevant equation individual weights n1+n2+n3+n4+n5 = total weight total weighed together N = total weight 3. The attempt at a solution I think weighing individually is more precise, but we weigh things together because the loss error is negligible.
