Answer
The total weight is 55 g.
The net weight is 50 g.
The weight of one paper clip is 0.5g.
Work Step by Step
Move the decimal to convert mg to g.
$500mg=0.5g$
Multiply by the number of paper clips to find the net weight.
$0.5g\times100=50g$
Add the weight of the packaging to find the total weight.
$50g+5g=55g$
