213 g
D
639 g
Verified step by step guidance1
Identify the molar mass of glucose (C6H12O6) by summing the atomic masses of all atoms in the formula: 6 carbons, 12 hydrogens, and 6 oxygens. Use the atomic masses: C = 12.01 g/mol, H = 1.008 g/mol, O = 16.00 g/mol.
Calculate the molar mass of glucose using the formula: \(\text{Molar mass} = (6 \times 12.01) + (12 \times 1.008) + (6 \times 16.00)\) g/mol.
Use the relationship between moles, molar mass, and mass: \(\text{Mass} = \text{Moles} \times \text{Molar mass}\).
Substitute the given number of moles (3.55 moles) and the calculated molar mass into the equation: \(\text{Mass} = 3.55 \times \text{Molar mass}\).
Perform the multiplication to find the mass of glucose in grams corresponding to 3.55 moles.
