Explanation:

Water, or H20, starts boiling at 100ºC.

Nitrogen, or N2, starts boiling at -195.8ºC.

Carbon monoxide, or C0, starts boiling at -191.5ºC.

When we place these in order from decreasing boiling point:

-195.8º goes first, then -191.5º, and 100º goes last.

What is the density of a sample of a substance with a volume of 120ml<br> and a mass of 90g?
tigry1 [53]

Answer:

<h3>The answer is 0.75 g/mL</h3>

Explanation:

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

density =  \frac{mass}{volume}  \\

From the question

mass = 90 g

volume = 120 mL

We have

density =  \frac{90}{120}  =  \frac{9}{12}  =  \frac{3}{4}  \\

We have the final answer as

<h3>0.75 g/mL</h3>

Hope this helps you
