<h2>Answer:</h2>

1.0783*10^{28}(atoms).

<h2>Explanation:</h2>

<em>Since I don't have access to "Appendix A", I'll solve the problem using data from the periodic table.</em>

<em />

<h3>1. Determine the molar mass of iron.</h3>

<em>According to the periodic table, the molar mass of iron is:</em>

55.845g/mole.

<h3>2. Convert 1 tonne to grams.</h3>

1(tonne)*1000=1000kg\\1000kg*1000=1000000g=10^6g

<h3>3. Apply rule of 3.</h3>

55.845g ----------- 1 mole

10^6g ----------- x

x=\frac{10^6*1}{55.845}=17906.7061(moles)

<h3>4. Determine the amount of atoms.</h3>

<em>Considering that there are, approximately, </em>6.022*10^{23} atoms in a mole of any element, apply another rule of 3.

1 mole --------------------- 6.022*10^{23}(atoms)

17906.7061(moles) --------------------- x

x=\frac{17906.7061*6.022*10^{23}}{1}=1.0783*10^{28}.

Setler [38]

The Engineers in Russia invented a new way to create colorful art with constructivist art.

<h3>What is constructivist art?</h3>

Constructivist art was aimed to reflect modern industrial society and urban space in art. It uses industrial production forms and modest materials for its art production.

The constructivists proposed to replace traditional art's with a focus on construction as Engineers rather than a painter.

Therefore, the Engineers in Russia invented a new way to create colorful art with constructivist art using construction.
