Question

54.5 mL of liquid gallium metal is poured into a graduated cylinder. The gallium filling the graduated cylinder weighs 10.686 g. From this information, calculate the density of the liquid gallium.

Answer 1

Answer:

The answer is 0.20 g/mL

Explanation:

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

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

From the question

mass = 10.686 g

volume of liquid gallium = 54.5 mL

So we have

$density = \frac{10.686}{54.5} \\ = 0.1960733944...$

We have the final answer as

0.20 g/mL

Hope this helps you
