Question

assuming that all baggies are the same size, which of the following would have the greatest density? a baggie with 10 pennies in it a baggie with 20 pennies in it a baggie with 5 pennies in it all baggies would be equal in density

Explanation:

Step1: Recall density formula

Density $
ho=\frac{m}{V}$, where $m$ is mass and $V$ is volume. The baggies are of the same size, so $V$ is constant.

Step2: Compare masses

More pennies mean greater mass. Since density is directly - proportional to mass when volume is constant, the baggie with more pennies has greater density.

Answer:

a baggie with 20 pennies in it
