Answer:
2.6 g/cubic centimeter
Explanation:
Given :
Weight of the quartz = 13 gram
Original level of water = 30mL
Level of water after quartz was is placed inside the cylinder = 35 mL
Therefore rise in water = 35 - 30 = 5 mL
We known that 1 mL = 1 cubic centimeter
And density = mass / volume
Therefore, density of the quartz is = 13/5
= 2.6 g/ cubic centimeter
I think the answer would be C
