andrezito [222]4 years ago
8 0

Answer:

0.599800731 moles or 33.4988708 grams

Explanation:

You are given the number of atoms. To convert to moles, divide by the number of atoms in a mole:

(3.612*10^23 atoms)/(6.022*10^23 atoms per mole) = 0.599800731 moles

Then, multiply the number of moles by the molar mass of Fe (iron).

(0.599800731 moles)*(55.85 grams per mole) = 33.4988708 grams

Which statement below correctly describes how amino acids join?
Shtirlitz [24]

Answer:

Amino acids join by linking the acid group of one amino acid to the amino group of another.

Explanation:

Amino acids are organic molecules that form the basic molecules for making proteins and there are. An amino acid comprises of an acidic carboxyl (-COOH) functional group and an amino group (-NH2)  as well as a side an organic side chain (R group).

In the formation of proteins, several amino acids join together by the formation of peptide bonds between each amino acids to form a long polypeptide. These peptide bods are formed by the linking of the acidic carboxyl group of one amino acid to the amino group of another amino acid, during this process water is removed.

A friend tells you that plants grow and gain mass only because of the nutrients they pull out of the soil. It this statement tru
Nutka1998 [239]
The statement that the friend made is not true. most of the mass of the plant is from carbon. the carbon comes from carbon dioxide which is used during photosynthesis. the left over carbon from photosynthesis is used to to help the plant gain mass. there is a process for this which is called cellular respiration

Calculate molecules in 1dm^3 of oxygen
Archy [21]

Number of molecules in 1 dm³ Oxygen = 2.71 x 10²²

<h3>Further explanation</h3>

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

The mole is the number of particles contained in a substance

1 mol = 6.02.10²³

1 dm³ of oxygen = 1 L Oxygen

  • mol Oxygen :

\tt \dfrac{1}{22.4}=0.045`mol

  • molecules of Oxygen :

n=mol=0.045

No = 6.02.10²³

\tt N=n\times No\\\\N=0.045\times 6.02\times 10^{23}\\\\N=2.71\times 10^{22}
