Hmm, it's not C. I wish people don't guess when they're trying to help. In any case, CoC says we don't give direct answers. Hint:First find the volume of the marble, then divide the mass by the volume just found to get the density in g/mL.
Do you know the volume of the marble, by reading the difference in liquid levels of the graduated cylinder?
40 and a hlaf
Before immersing the marble, the left reads 40 mL. After the marble is dunked in, the right reads???
Yes, I read 48 mL. there are 5 spaces between 40 and 50, so each graduation stands for 2 mL, so the volume of liquid AND marble is 48 mL. So from this, can you find the volume of the marble?
so its 48 and 40?
Yes, the difference gives the volume of the marble, since the level went up 8 mL after putting the marble in the liquid.
Finally, you can find the mass density by dividing the mass by the volume. The answer is one of the four choices.
What is the mass of the marble, and what is the volume (which we found earlier)?
15 and 8
Exactly! You're welcome!
