P = 1.5atm ≈ 1519.88hPa
V = 8.56L
R = 83.1 [hPa*L] / [mol*K]
T = 0°C =273K

pV = nRT   |:RT

n = pV / RT

n = [1519.88hPa*8.56L] / [83.1 [hPa*L] / <span>[mol*K] * 273K]
n </span>≈ <u>0.57mol</u><span><u> </u></span>

Determine the element of lowest atomic number that contains a complete d subshell in the ground state. element symbol:
allsm [11]

The component with the most low atomic number that contains a total d-subshell in the ground state is copper. Copper's electron arrangement is [Ar]3d104s1 [ A r ] 3d 10 4 s 1 .  

Further Explanation:  

atomic number:  

The nuclear number or proton number (image Z) of a synthetic component is the quantity of protons found in the core of a particle. It is indistinguishable from the charge number of the core. The nuclear number particularly distinguishes a compound component. In an uncharged iota, the nuclear number is likewise equivalent to the quantity of electrons.  

The elemenents of the intermittent table arranged by atomic mass:  

atomic Mass    Name substance element          Number  

1.0079                          Hydrogen                            1  

4.0026                            Helium                                    2  

6.941                           Lithium                                    3  

9.0122                           Beryllium                                    4  

atomic number speak to:  

The nuclear number (otherwise called the proton number) is the quantity of protons found in the core of an iota. It is customarily spoken to by the image Z. The nuclear number exceptionally distinguishes a substance component. In a particle of impartial charge nuclear number is equivalent to the quantity of electrons.  

Meaning of subshell:  

A subshell is a subdivision of electron shells isolated by electron orbitals. Subshells are marked s, p, d, and f in an electron design.

Subject: chemistry

The mass percent of each compound is

  • (NaBr*2H2O)=85.71 percent
  • (MgBr2*6H2O)=14.29 percent

<h3>The mass percent equation is as follows.</h3>

The formula mass percent is the most effective way to express mass percent: mass percent = (mass of chemical x total mass of compound) times 100. Add 100 to the top value to get the value expressed as a percentage.

<h3>What percentage by mass does a solution have?</h3>

By multiply the grams of solute per gram of solution by 100, it is possible to get the mass percent of a solution.

The molar mass of each element and the mass of each element contained in a mole of the compound are both solved for in the Mass Percent formula.
