Question

In a science experiment, Shelly has to weigh a compound in grams. The balance in her school measures in milligrams (mg). Shelly finds that the weight of the compound is 8,450 mg. What is the value in grams (g) that Shelly should enter?

1) 0.845 g
2) 8.45 g
3) 84.5 g
4) 845 g

Answer 1

Shelly's compound weight of 8,450 mg converts to 8.45 g when divided by 1,000 since there are 1,000 milligrams in a gram. Option 2.

Step-by-step explanation:

In the science experiment, Shelly has weighed a compound and found that it is 8,450 mg. To convert milligrams to grams, we need to remember that there are 1,000 milligrams in 1 gram. Therefore, to convert Shelly's measurement to grams, we divide the number of milligrams by 1,000.

The calculation will be:

8,450 mg ÷ 1,000 = 8.45 g

So, the correct value in grams that Shelly should enter is 8.45 g. Option 2.
