How many atoms are in 3.20 moles of carbon

Answers

Answer 1

Answer:

Answer:

19.264× $10^(23)$ atoms are present in 3.2 moles of carbon.

Explanation:

It is known that one mole of each element is composed of Avagadro's number of atoms. This is same for all the elements in the periodic table.

So, as 1 mole of any element = Avagadro's number of atoms = 6.02× $10^(23)$ atoms

It is as simple as understanding a dozen of anything is equal to 12 pieces of that object.

As here the moles of carbon is given as 3.20 moles, the number of atoms in this mole can be determined as below.

1 mole of carbon = 6.02 × $10^(23)$ atoms

Then, 3.20 moles of carbon = 3.20 × 6.02 × $10^(23)$ atoms

Thus, 19.264× $10^(23)$ atoms are present in 3.2 moles of carbon.

How does Silicon shape our technological reality

Answers

Silicon shapes our technological reality because computer chips are made out of silicon. Different computer parts, are made out of silicon chips, tablets, phones, different electronic devices, everything has some silicon in them. Without silicon we would (currently) not have any of those. That is how silicon shapes our technological reality :)

The silicon uses in :

1- Micro-chips.

2- Motherboards

3- components on nano-technologies

4- tablet

5- Phones

The explanation:

- When the silicon incorporated into electronics, They are termed as silicon wafers. It is used as a semiconductor.

- And when it combined with the other conductors this process called doping and become ideal to make transistors and be able to amplify electric signals.

That's how Silicon shape our technological reality.

If I initially have a gas at a pressure of 12 atm, volume of 23 liters, and temperature of 200 K, and then I raise the pressure to 14 atm and increase the temperature to 300 K, what is the new volume of the gas?

Answers

Answer : The volume of gas will be 29.6 L

Explanation:

Combined gas law is the combination of Boyle's law, Charles's law and Gay-Lussac's law.

The combined gas equation is,

$(P_1V_1)/(T_1)=(P_2V_2)/(T_2)$

where,

$P_1$ = initial pressure of gas = 12 atm

$P_2$ = final pressure of gas = 14 atm

$V_1$ = initial volume of gas = 23 L

$V_2$ = final volume of gas = ?

$T_1$ = initial temperature of gas = 200K

$T_2$ = final temperature of gas = 300K

Now put all the given values in the above equation, we get the final pressure of gas.

$(12atm* 23L)/(200K)=(14* V_2)/(300K)$

$V_2=29.6L$

Therefore, the new volume of gas will be 29.6 L

Hello!

We have the following data:

P1 (initial pressure) = 12 atm

V1 (initial volume) = 23 L

T1 (initial temperature) = 200 K

P2 (final pressure) = 14 atm

T2 (final temperature) = 300 K

V2 (final volume) = ? (in L)

Now, we apply the data of the variables above to the General Equation of Gases, let's see:

$(P_1*V_1)/(T_1) =(P_2*V_2)/(T_2)$

$(12*23)/(200) =(14*V_2)/(300)$

$(276)/(200) =(14\:V_2)/(300)$

multiply the means by the extremes

$200*14\:V_2 = 276*300$

$2800\:V_2 = 82800$

$V_2 = \frac{82800\!\!\!\!\!\!\!\frac{\hspace{0.4cm}}{~}}{2800\!\!\!\!\!\!\!\frac{\hspace{0.4cm}}{~}}$

$V_2 \approx 29.57142857... \to \boxed{\boxed{V_2 \approx 30\:L}}\:\:\:\:\:\:\bf\blue{\checkmark}$

*** Note: the approximation rule says that when the number before the digit 5 is odd, the previous value is raised to the next even number

Answer:

The new volume is approximately 30 Liters
