Question: What is the number of atoms in 2 moles of aluminum (Al)? (2044)

Options:

Correct Answer: 1.2044 x 10^24

Solution:

Number of atoms = moles x Avogadro\'s number = 2 moles x 6.022 x 10^23 atoms/mole = 1.2044 x 10^24 atoms.

What is the number of atoms in 2 moles of aluminum (Al)? (2044)

What is the number of atoms in 2 moles of aluminum (Al)? (2044)

Step 1: Understand that 1 mole of any substance contains a specific number of particles, which is called Avogadro's number.
Step 2: Know that Avogadro's number is approximately 6.022 x 10^23 particles per mole.
Step 3: Identify that you have 2 moles of aluminum (Al).
Step 4: To find the total number of atoms, multiply the number of moles (2) by Avogadro's number (6.022 x 10^23).
Step 5: Perform the multiplication: 2 moles x 6.022 x 10^23 atoms/mole.
Step 6: Calculate the result: 2 x 6.022 = 12.044, and keep the exponent (10^23) the same.
Step 7: Write the final answer in scientific notation: 1.2044 x 10^24 atoms.
