Circle the letter of the unit of mass commonly used in chemistry that equals 1/1000 Kilogram.

a)gram
b)Milligram
c)milliliter

Kilo is 1000. What is 1/1000 of 1000?

gram

To find the answer to this question, we need to understand the concept of metric prefixes. In the metric system, prefixes are added to the base units to represent different orders of magnitude.

The prefix "kilo" represents 1000. Therefore, if we want to find 1/1000 of 1000, we divide 1000 by 1000, which equals 1.

Now, let's think about the options provided:

a) gram: A gram is the base unit of mass in the metric system. It is not equal to 1/1000 kilogram.

b) milligram: A milligram is a unit of mass commonly used in chemistry. The prefix "milli" represents 1/1000. Therefore, 1 milligram is equal to 1/1000 of a gram or 1/1000000 of a kilogram.

c) milliliter: A milliliter is a unit of volume, not mass.

Based on this information, the correct answer is b) Milligram.
