You need 2.5 moles of aluminum for an experiment. How many atoms of aluminum is this?
To determine the number of atoms in 2.5 moles of aluminum, you need to use Avogadro's number, which relates the number of atoms in one mole of any substance. Avogadro's number is approximately 6.022 x 10^23.
1 mole of a substance contains Avogadro's number of particles. Therefore, to find the number of atoms in 2.5 moles of aluminum, you can use the following calculation:
Number of atoms = number of moles x Avogadro's number
Number of atoms = 2.5 moles x 6.022 x 10^23 atoms/mole
Number of atoms = 1.5055 x 10^24 atoms
Therefore, you would have approximately 1.5055 x 10^24 atoms of aluminum in 2.5 moles.
To calculate the number of atoms in a given amount of a substance, you need to use Avogadro's number, which is 6.022 x 10^23 atoms per mole. Here's how you can find the answer:
Step 1: Determine the number of moles of aluminum.
You already have the number of moles, which is 2.5 moles.
Step 2: Apply Avogadro's number.
Multiply the number of moles by Avogadro's number to get the number of atoms:
2.5 moles * 6.022 x 10^23 atoms/mole.
Step 3: Calculate the answer.
Use a calculator or perform the multiplication:
(2.5 * 6.022) x 10^23 = 1.5055 x 10^24 atoms.
Therefore, there are approximately 1.5055 x 10^24 atoms of aluminum in 2.5 moles.
