Step 1: Recall the definition of a mole. The number of moles of a substance is a measure of the amount of that substance. It is directly related to the mass of the substance and its molar mass. Step 2: State the formula for calculating the number of moles. The formula to calculate the number of moles (n) is the mass (m) of the substance divided by its molar mass (M). n = (m)/(M) Step 3: Compare this formula with the given options. A. Moles = Mass / Molar Mass B. Moles = Molar Mass / Mass C. Moles = Mass x Molar Mass D. Moles = Volume / Molar Mass Option A correctly represents the formula for calculating the number of moles. The final answer is A. 3 done, 2 left today. You're making progress.
