Calculate moles of Fe in 5.22 X 10^22 atoms of Fe?

Chemistry
1 answer:
Setler [38]2 years ago
5 0

Answer:

The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.

Explanation:

Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension, so it is considered a pure number that allows describing a physical characteristic without an explicit dimension or unit of expression. Avogadro's number applies to any substance.

Then you can apply the following rule of three: if 6.023*10²³ atoms are contained in 1 mole, 5.22*10²² atoms are contained in how many moles?

amount of moles=\frac{5.22*10^{22}atoms * 1 mole}{6.023*10^{23}atoms}

amount of moles= 0.0867

<u><em>The amount of moles of Fe in 5.22*10²² atoms of Fe is 0.0867.</em></u>

Alveolar air (a mixture of nitrogen, oxygen, and carbon dioxide) has a total pressure of 0.998 atm. If the partial pressure of o
Vadim26 [7]

Answer:

22.8 mmHg

Explanation:

According to Dalton's law of partial pressures, the total pressure of a mixture of gases is obtained as the sum of the partial pressures if all the individual gases present in the mixture.

Since the total pressure of gases in the mixture is 0.998 atm, the partial pressure of carbon dioxide is;

PCO2 = [Ptotal - (PO2+ PN2)]

Hence;

PCO2 = [0.998 - (0.198 + 0.770)]

PCO2 = 0.03

Since

1 atm = 760 mmHg

0.03 atm = 0.03 × 760 /1

=22.8 mmHg

Describe how a homogeneous moisture differs from a heterogeneous mixture
Shalnov [3]

Answer:

Explanation:

Mixture: is combination of one or more substances mix together.

• The properties of the mixture are not same and contains the properties of all those component present in it.

• it is a combination of one or more Pure substances and can be separated by simple physical methods.

• it have varying boiling and melting point

Homogeneous Mixture: are those which are not distinguish by naked eye but can be separated into its components by physical means.

The components of a homogeneous mixture are in the same phase oar in dissolved form so it look like one component.

Examples are:

• Salt water is mixture of water and NaCl and can be separated by physical mean.

• Air: mixture of gases

Heterogeneous mixture: are those which can be distinguishing by naked eye and can be separated into its components by physical means.

The component of heterogeneous mixture not fully mixed are different in color or different in phases or not soluble. So one can easily see the difference in the component of the mixture

Examples is

• mixture of salt and sand

• mixture of water and sand

Bingel [31]

Answer:

Hexose category and ketohexose category

Explanation:

The classification of the Carbohydrate tagatose by carbonyl group is that it is a monosaccharide and has a hexose structure hence it belongs to the Hexose category

Based on the number of carbon atoms the structure has a ketofunctionality hence it is classified under the ketohexose category

Attached below is the remaining part of the solution
