i have a test and im trying to find out how i can solve this on the review sheet so i dont fail and she didnt explain it

the answer is 1.79x10(-5 power)

by the way could i get some help on significatn figures?

Answer 1

Remember:

Density = mass/volume

You want volume, so

volume = mass / density convert mass into kg.

Volume = 35.4*10^-3/1.98*10^3

Volume = 1.79*10^-5 mm³

When you submit a question, please ensure that you provide all the info. I had to guess that the mass was 35.4 grams
