Recall one of the rules for significant figures

A final zero or trailing zeros in the decimal portion ONLY are significant

24.00 mg has four significant figures

2,4, 0 and 0

24.00 mg when converted to grams is 0.024 g

0.024 only has 2 significant figures, therefore we need to add 2 more zeroes at the end of 4

0.024 g → 0.02400 g
