Density of any substance can be measured using the following rule:
density = mass / volume

Since in this question, the volume of mercury is equal to the volume of water but still the mass of mercury is greater than the mass of water. 
Therefore, by substituting in the density equation, we will conclude that mercury is higher density than water.

The answer is:
<span>Mercury is denser than water</span>

Predict the products that will be formed by the reaction below. Al(s)+Na2SO4(s)—&gt;
Ostrovityanka [42]

Answer:

Al₂(SO₄)₃ and Na

Explanation:

Al has a charge of +3, Na has a charge of +1 and SO₄ has a charge of -2. Since cations and anions will bond we know that Al will bond with SO₄ leaving Na by itself (since this is a single replacement reaction). When Al bonds with SO₄ it makes aluminum sulfate which is Al₂(SO₄)₃ and Na will be left by itself.

A block of iron has a mass of 150 g and a volume of 20 ml. What is the density of iron? *
shtirl [24]

Answer:

<h3>The answer is 7.50 g/mL</h3>

Explanation:

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

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

From the question

mass of iron = 150 g

volume = 20 mL

We have

density =  \frac{150}{20}  =  \frac{15}{2}  \\

We have the final answer as

<h3>7.50 g/mL</h3>

Hope this helps you
