Taking into account the definition of density, the density of the sample is 0.5 \frac{g}{mL}.

It is necessary yo know that density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density allows you to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density=\frac{mass}{volume}

In this case, you know:

  • mass= 6 g
  • volume= 12 mL

Then, replacing in the definition of density:

density=\frac{6 g}{12 mL}

Solving:

<u><em>density= 0.5 </em></u>\frac{g}{mL}<u><em /></u>

Finally, the density of the sample is 0.5 \frac{g}{mL}.

For the first ionization energy for an N2 molecule, what molecular orbital is the electron removed from
olga55 [171]

Answer:

p orbital.

Explanation:

Valence electrons are the electrons in an atom holding the very last orbital which is used in chemical bonding with other elements. Their existence could define the chemical properties of that atom.

During the first energy in ionization of an N2 molecule the molecular orbital from which the electron could be extracted is the only one with the highest energy level. Nitrogen has its outermost orbital (p) containing three valence electrons. Each orbital is only half filled, and thus it is unstable Thus, the electron mission must have been removed from p orbital.

Upon consideration of the SiO2–Al
Grace [21]

The phase's composition is as follows: 27

What is the alloy's composition?

Both have mass fractions of w a = w b = 0.5.

A-B alloy composition; C o = 57 wt% B - 43 wt% A

C b = 87 wt% B - 13 wt% A is the new phase composition.

Using the Lever rule, we can calculate the mole fraction (x i) or mass fraction (w i) of each phase of a binary equilibrium phase as follows:

W a = W b = 0.5

This provides us with;

0.5 = (C b - C o)/(C b - C a)

(87 - 57)/(87 - C a) = 0.5

30/0.5 = 87 - C a

60 = 87 - C a

C a = 87 - 60

C a = 27
