If 60 grams of a liquid takes up 120ml how dense is the liquid

Black_prince [1.1K]

Answer:

<h2>Density = 0.5 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

mass = 60 g

volume = 120 mL

Substitute the values into the above formula and solve

That's

<h3> $Density = \frac{60}{120} \\ = \frac{1}{2}$ </h3>

We have the final answer as

<h3>Density = 0.5 g/mL</h3>

Hope this helps you
