To determine the number of moles of ethanol (C2H5OH), we first calculate its molar mass using the atomic masses: C (12.01 g/mol) contributes (2 × 12.01) = 24.02 g/mol, H (1.01 g/mol) contributes (6 × 1.01) = 6.06 g/mol, and O (16.00 g/mol) contributes 16.00 g/mol, resulting in a total molar mass of 46.08 g/mol for ethanol. Using the formula for moles (\( \text{moles} = \frac{\text{mass}}{\text{molar mass}} \)), we find that 30 g of ethanol corresponds to approximately 0.65 moles (30 g / 46.08 g/mol).
