Determining the Mass of Precious Stones and Pearls

To determine the mass of precious stones and pearls, a unit of mass called a carat is used. One carat is equal to one-fifth of a gram. If the mass of a large pearl is given as 20 carats, we can calculate its mass in grams.

To convert carats to grams, we can use the following conversion factor:

1 carat = 0.2 grams.

Now, let's calculate the mass of the large pearl in grams:

Mass of the large pearl = 20 carats * 0.2 grams/carat = 4 grams.

Therefore, the mass of the large pearl is 4 grams.
