Answer:
<h2>0.93 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%5C%5C)
From the question
mass = 37.2 g
volume = 40 mL
We have
![density = \frac{37.2}{40} \\ = 0.93](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B37.2%7D%7B40%7D%20%20%5C%5C%20%20%3D%200.93)
We have the final answer as
<h3>0.93 g/mL</h3>
Hope this helps you
A incline plane is a flat inclined surface. You can stick a rope in the pulley and pull one side and the other side will lift something! They are both simple machines! The difference is a incline plane is a ramp and things go up or down and the pulley lifts something with force of your weight!!
