what steps do i take when trying to figure out how many atoms of copper are contained in 1.15 moles of Cu?
To determine the number of atoms of copper contained in 1.15 moles of Cu, you need to follow these steps:
1. Start with the given quantity: 1.15 moles of Cu.
2. Use Avogadro's number, which states that there are 6.022 x 10^23 atoms in one mole of any substance. This number is based on the concept of a mole being the amount of substance that contains the same number of atoms, molecules, or ions as there are in exactly 12 grams of carbon-12.
3. Multiply the given quantity (1.15 moles) by Avogadro's number (6.022 x 10^23) to convert moles into the number of atoms. This conversion factor gives you the relationship between moles and atoms: 1 mole = 6.022 x 10^23 atoms.
Calculation: 1.15 moles Cu x (6.022 x 10^23 atoms Cu / 1 mole Cu)
4. Perform the calculation to find the number of atoms of copper:
Number of atoms = 1.15 moles Cu x (6.022 x 10^23 atoms Cu / 1 mole Cu)
5. The resulting value will give you the number of atoms of copper present in 1.15 moles of Cu.
