Question

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?

Answer 1

m = 7.5 grams

Step-by-step 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,

`d=(m)/(V)\\\\m=d* V\\\\m=1.5* 5\\\\m=7.5\ g`

So, the mass of the rock is 7.5 grams.
