Answer
The original statement is false. A 100-mg object weighs less than a 2-ounce object.
Work Step by Step
$1~g = 1000~mg$
$1~oz \approx 28~g$
We can convert 100 mg to units of ounces.
$100~mg = \frac{100~mg}{1}\times \frac{1~g}{1000~mg}\times \frac{1~oz}{28~g}$
$100~mg = 0.0036~oz$
We can see that the original statement is false. A 100-mg object weighs less than a 2-ounce object.
