To calculate the number of atoms in 3.01 x 10²³ atoms of copper (Cu), you simply interpret the notation. The expression indicates that there are 3.01 times 10 raised to the power of 23 atoms, which is a way to express a large quantity, specifically Avogadro's number (approximately 6.022 x 10²³). Thus, 3.01 x 10²³ atoms of copper is approximately half of Avogadro's number, indicating that you have about half a mole of copper atoms.
