Answer:
mole ratio, which is equivalent to a 1;1 mole ratio, to a gram ratio. This means that when the reaction consumes 84.03 g of carbon monoxide, it should theoretically produce 132.03 g of carbon dioxide. Use this gram ratio to calculate the theoretical yield for your reaction.
Explanation:
The molality of the isopropyl alcohol in the solution is 13.95 m
<h3>Assumption</h3>
- Let the mass of the solution be 100 g.
- 45.6% by mass isopropyl alcohol = 45.6 g
- Mass of solvent = 100 – 45.6 = 54.4 g
<h3>Determination of the mole </h3>
- Mass of isopropyl alcohol = 45.6 g
- Molar mass of isopropyl alcohol = 60.11 g/mol
- Mole of isopropyl alcohol =?
Mole = mass / molar mass
Mole of isopropyl alcohol = 45.6 / 60.11
Mole of isopropyl alcohol = 0.759 mole
<h3>How to determine molality </h3>
- Mole of isopropyl alcohol = 0.759 mole
- Mass of solvent = 54.4 g = 54.4 / 1000 = 0.0544 Kg
Molality = mole / mass of solvent
Molality = 0.759 / 0.0544
Molality = 13.95 m

<h3><u>Answer;</u></h3>
<em> D) It can be mass produced.</em>
<h3><u>Explanation;</u></h3>
- <em><u>Synthetic materials</u></em> are those materials that are <em><u>man-made, that is they are synthesized in the lab or in industries.</u></em> They include synthetic fibers such as nylon, polyester and acrylic among others.
- <em><u>Synthetic materials</u></em> have a range of advantages over natural materials. For example, synthetic materials are durable than natural ones, they are cheap, they do not shrink and also resistant to chemicals among others.
- Additionally, synt<em><u>hetic materials such as synthetic fibers they can be mass produced in industries or in the labs. </u></em>
The correct option is B.
Matters exist in three phases, which are solid, liquids and gas. These three phases behaves differently based on their structures. Solids have definite shape and volume and their particles are tightly connected, so their particles vibrate about a fixed position. Liquids have definite volume but no shape. The inter molecular force among liquid particles is not as strong as that of solid, so the particles can move around slowly. Gases has no shape and no volume. The inter molecular force in gas particles are negligible and thus, they move about freely and randomly and fill all the available spaces.
