<h2>Hello!</h2>

The answer is: -97.23° C

<h2>Why?</h2>

Applying the Charles and Gay-Lussac's Law we have that:

\frac{V}{T}=k

Where:

<em>k </em>is the proportionality constant

<em>v</em> is the volume of the gas

<em>t</em> is the temperature of the gas

We also have the following relation:

\frac{V1}{T1}=\frac{V2}{T2}

Since we need to know the new temperature (T2) we can find it using the last equation, so:

\frac{V1}{T1}=\frac{V2}{T2}\\\\T2=\frac{V2*T1}{V1}=\frac{16.2L*278K}{25.6L}=175.92K

We are asked to find the temperature in Celsius degrees, we must convert the result:

Celsius=K-273.15=175.92-273.15=-97.23

Therefore, the temperature is -97.23° C

Have a nice day!

What is equal to the number of particles in 36 grams of carbon-12?
HACTEHA [7]

Answer:

3 moles

Explanation:

To solve this problem we will  use the Avogadro numbers.

The number 6.022×10²³ is called Avogadro number and it is the number of atoms, ions or molecules in one mole of substance.  According to this,

1.008 g of hydrogen = 1 mole =  6.022×10²³  atoms.

18 g water = 1 mole = 6.022×10²³ molecules

we are given 36 g of C-12. So,

12 g of C-12 = 1 mole

24 g of C-12 =  2 mole

36 g of C-12 = 3 mole

So 3 moles of C-12 equals to the number of particles in 36 g of C-12.
