A rock with a mass of 70 grams is dropped into a graduated cylinder with 30 mL of water in it. The water level rose to 35 mL calculate the density of the rock in g/mL

14 g/mL

Explanation:

The formula to find the density is p=m/v.

The mass is 70 grams. The volume is 5 due the the fact that we subtracted the final volume to the initial volume. Then we divide 70 by 5 and you'll get 14 as your answer.

I hope this helps in the future! Have a great day.

Equation is set below:

p= m/v

p=70/5

p= 14

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
