Shaila is collecting data to calculate the density of a piece of wood. First, she
zzz [600]

Answer:

Explanation:

Remark

You have 2 facts that you got from the experiment. The first is that the mass of the wood is 63.85 grams and the volume can be calculated.

From there, the desity can be found.

Givens

m = 63.85 grams

vo = 50 mL

vf = 125 mL

Solution

Volume = vf - vo

Volume = 125 mL - 50 ml. This gives you the amount of water that has been moved aside (called displaced)

volume = 75 mL

D = 63.85 grams/ 75 mL

D = 0.851 grams / mL

Some woods actually do have a density less than 1 which is the density of water. These woods float.

An object has a mass of 6.8 g and volume of 34 mL. What is the density of the object?​
jenyasd209 [6]

Answer:

<h2>Density = 0.2 g/mL</h2>

Explanation:

The density of a substance can be found by using the formula

<h3>Density =  \frac{mass}{volume}</h3>

From the question the points are

mass = 6.8 g

volume = 34 mL

Substitute the values into the above formula and solve

That's

<h3>Density =  \frac{6.8}{34}</h3>

We have the final answer as

<h3>Density = 0.2 g/mL</h3>

Hope this helps you
