검증된 단계별 안내1
Identify the given information: mass of copper (Cu) is 65.8 g, and the atomic mass of Cu is 63.5 g/mol.
Recall the formula to convert mass to moles: \(\text{moles} = \frac{\text{mass (g)}}{\text{molar mass (g/mol)}}\).
Substitute the given values into the formula: \(\text{moles of Cu} = \frac{65.8}{63.5}\).
Perform the division to find the number of moles of copper present.
Compare the calculated value with the given options to select the correct number of moles.
