Answer
The original statement is false. A 50-gram object weighs less than a 2-ounce object.
Work Step by Step
$1~oz \approx 28~g$
We can convert 50 grams to units of ounces.
$50~mg = \frac{50~g}{1}\times \frac{1~oz}{28~g}$
$50~mg = 1.79~oz$
We can see that the original statement is false. A 50-gram object weighs less than a 2-ounce object.
