Question

Astronauts use a tool in space that weighs 5 ounces on Earth. How many grams does the tool weigh? Round your answer to the nearest hundredth.

The tool weighs
grams.

Answer 1

To convert the weight of the tool from ounces to grams, we can use the conversion factor from the table. There are 28.35 grams in 1 ounce.

The tool weighs 5 ounces, so we can calculate its weight in grams as follows:

\[ \text{Weight in grams} = 5 , \text{ounces} \times 28.35 , \text{grams/ounce} \]

Calculating that gives:

\[ \text{Weight in grams} = 5 \times 28.35 = 141.75 , \text{grams} \]

Thus, the tool weighs 141.75 grams.
