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

First you need to find how many grams is 1 ounce. 1o z. is 28.35 g, then you need to multiply 28.35 g by 5 which is 141.75. you need to round it to the nearest hundred so it is about 142 grams.

the key here would be

1 oz. = 28.35g or 1 oz. = 28 g

Um. That is quite difficult considering that in space the gravitational pull effects weight. Are we talking deep space? Or we just talking about orbit of earth?
