Explanation:

<h2>(a).</h2>

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

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

From the question

mass of metal = 14 g

volume = 2.98 mL = 2.98 cm³

It's density is

density =  \frac{14}{2.98}  \\  = 4.69798657...

We have the answer as

4.70 g/cm³

<h2>(b).</h2>

The metal is not copper since it's density is less than that of copper.

Hope this helps you

Consider the chemical formula for one unit of aluminum sulfate, Al2(SO4)3. How many total atoms would be present in 22 units of
EastWind [94]

Answer:

1.32×10²⁵ atoms of sulfate are contained in 22 units of it

Explanation:

1 unit = 1 mol

Al₂(SO₄)₃ → Aluminum sulfate

As 1 unit = 1 mol, 1 unit has 6.02×10²³ atoms of aluminum sulfate.

Let's make a rule of three:

1 unit of Al₂(SO₄)₃ contains 02×10²³ atoms

Then, 22 units of Al₂(SO₄)₃ must contain (22 . 6.02×10²³) / 1 = 1.32×10²⁵ atoms
