**Question 7 of 32** **Question:** What quantity in moles of iron atoms do you have if you have \(2.50 \times 10^{23}\) atoms of iron? (The mass of one mole of iron is 55.85 g.) **Answer Field:** 20 mol **Input Interface:** A numeric keypad with buttons labeled 1 through 9, 0, and additional buttons for a decimal point (.), a plus/minus sign (+/-), a backspace (X), a clear button (C), and an exponent notation button (x 10^). **Explanation:** In this question, the goal is to determine the number of moles of iron atoms from a given number of atoms. To calculate this, you can use Avogadro's number (\(6.022 \times 10^{23}\) atoms/mole). The formula is: \[ \text{Moles of iron atoms} = \frac{\text{Number of atoms}}{\text{Avogadro's number}} \] This page on an educational website presents learners with the question and a user-friendly interface to input their answers using the keypad.
