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 that 1 ounce is equal to 28.35 grams.

Given that the tool weighs 5 ounces, we can calculate its weight in grams as follows:

$$\text{Weight in grams}=5\text{ ounces}\times 28.35\text{ grams/ounce}$$

Now, performing the multiplication:

$$\text{Weight in grams}=5\times 28.35=141.75\text{ grams}$$

Therefore, the tool weighs 141.75 grams.
