PLS HELP QUICK GIVING 20 POINTS... If a rock has a mass of 1.5 - g / mL and displaces 5-mI. of water, what is the mass of the rock?

m = 7.5 grams

Explanation:

Given that,

The density of the rock, m = 1.5 g/mL

The volume displaced by the rock, V = 5 mL

We need to find the mass of the rock. The density of an object is equal to its mass divided by its volume. So,

So, the mass of the rock is 7.5 grams.

explanation:

vestigial organs (like your appendix) are organs that no longer serve a purpose.

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
