Taking into account the definition of avogadro's number,
2. 3.35 moles of aluminum contains 2.018ײ⁴ atoms.
3. 4.52 moles of CO₂ gas are in a 101.25 L container filled with CO₂ gas.
4. 13.7 moles of N₂ contain 383.6 grams.
<h3>2. How many atoms are in 3.35 moles of Aluminum?</h3>
Avogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 1 mole of aluminum contains 6.023×10²³ atoms, then 3.35 moles of aluminum contains how many atoms?
amount of atoms of aluminum= (6.023×10²³ atoms × 3.35 moles)÷ 1 mole
amount of atoms of aluminum=2.018ײ⁴ atoms
Finally, 3.35 moles of aluminum contains 2.018ײ⁴ atoms.
<h3>3.How many moles of CO₂ gas are in a 101.25 L container filled with CO₂ gas?</h3>
The STP conditions refer to the standard temperature and pressure. Pressure values at 1 atmosphere and temperature at 0 ° C are used and are reference values for gases. And in these conditions 1 mole of any gas occupies an approximate volume of 22.4 liters.
Then, you can apply the following rule of three: If by definition of the STP conditions 1 mole of CO₂ occupies a volume of 22.4 L, how many moles does 101.25 L occupy?
<u><em>amount of moles of CO₂= 4.52 moles</em></u>
4.52 moles of CO₂ gas are in a 101.25 L container filled with CO₂ gas.
<h3>4. What is the mass of 13.7 moles of N₂ gas?</h3>
The molar mass of substance is a property defined as its mass per unit quantity of substance, in other words, molar mass is the amount of mass that a substance contains in one mole.
In this case, the molar mass of N₂ is 28 g/mole. So, you can apply the following rule of three: If 1 mole of N₂ contains 28 grams, 13.7 moles of N₂ contain how much mass?
<u><em>mass= 383.6 grams</em></u>
13.7 moles of N₂ contain 383.6 grams.
