If the molar mass of methanol (CH_3OH) is 32.04 g/mol, what is the mass of a sample containing 56.6 moles of methanol?

• A. 1814 g
• B. 56.6 g
• C. 32.04 g
• D. 181.4 g

Answer: (A)

Verified step by step guidance

1. Identify the given information: the molar mass of methanol (CH\_3OH) is 32.04 g/mol, and the amount of substance is 56.6 moles.
2. Recall the relationship between mass, moles, and molar mass, which is given by the formula: \(\\text{mass} = \\text{moles} \\times \\text{molar mass}\).
3. Substitute the known values into the formula: \(\\text{mass} = 56.6 \\text{ moles} \\times 32.04 \\text{ g/mol}\).
4. Perform the multiplication to find the mass of the methanol sample (do not calculate the final number here, just set up the expression).
5. Express the final answer with the correct units (grams) since molar mass is in grams per mole and moles cancel out, leaving grams.
