How would 25.5 mg of DNA appear on an analytical balance?

When converting milligrams to grams, it's essential to remember the metric relationship between these two units. One gram is equivalent to 1000 milligrams. Therefore, to convert 25.5 milligrams into grams, you divide by 1000:

25.5 mg ÷ 1000 = 0.0255 g.

This conversion shows that 25.5 mg is indeed equal to 0.0255 g, which is how it would be displayed on an analytical balance set to read in grams. When measuring small quantities of substances, an analytical balance is designed to provide readings in grams and can handle such small amounts with high precision. This makes the value of 0.0255 g the correct representation of 25.5 mg in grams.
