SOLVE The density of a gas is 0.68 g/mL. What amount of space would 23.8 g of this gas occupy?
Contact [7]

Answer:

<h2>The answer is 35 mL</h2>

Explanation:

Density of a substance can be found by using the formula

Density(\rho) =  \frac{mass}{volume}

From the question we are finding the amount of space the gas will occupy that's the volume of the gas

Making volume the subject we have

volume =  \frac{mass}{Density}

From the question

mass = 23.8 g/mL

Density = 0.68 g/mL

Substitute the values into the above formula and solve

That's

volume =  \frac{23.8}{0.68}

We have the final answer as

<h3>35 mL</h3>

Hope this helps you

anyanavicka [17]

You didn’t show the cylinder containing water, so I created one that you can use as a model (see image).

The water level was originally at 37 mL.

Then you added the ball, and it displaced its volume of water.

The new volume reading is 52 mL, so

Volume of ball = volume of displaced water = 52 mL – 37 mL = 15 mL.
