Answer:

<h2>118,438.5 moles</h2>

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

$n = \frac{N}{L}\\$

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

$n = \frac{7.13 \times {10}^{28} }{6.02 \times {10}^{23} } \\ = 118438.538...$

We have the final answer as

<h3>118,438.5 moles</h3>

Hope this helps you

Answer:

Explanation:Explanation:

Your starting point here will be the ideal gas law equation

∣

−−−−−−−−−−−−−−−

, where

- the pressure of the gas

- the volume it occupies

- the number of moles of gas

- the universal gas constant, usually given as

0.0821

atm

⋅

mol

⋅

- the absolute temperature of the gas

Now, you will have to manipulate this equation in order to find a relationship between the density of the gas,

, under those conditions for pressure and temperature, and its molar mass,

You know that the molar mass of a substance tells you the mass of exactly one mole of that substance. This means that for a given mass

of this gas, you can express its molar mass as the ratio between

and

, the number of moles it contains

Similarly, the density of the substance tells you the mass of exactly one unit of volume of that substance.

This means that for the mass

of this gas, you can express its density as the ratio between

and the volume it occupies

The correct equation for the overall reaction can simply be obtained by adding the two separate equations together. Now when you add the two equations together, the overall K can be calculated by multiplying the individual K values. Therefore:<span>

K(overall) = K1 * K2 </span>

K(overall) = (1.6 x 10^-10) * (1.5 x 10^7)

<span>K(overall) = 2.4 x 10^-3</span>
