Question

1. the molar mass of glucose (c6h12o6)

• a) 12,g/mol
• b) 180,g/mol
• c) 44,g/mol
• d) 36,g/mol

Explanation:

Step1: List atomic masses

Atomic mass of C = $12\ \text{g/mol}$, H = $1\ \text{g/mol}$, O = $16\ \text{g/mol}$

Step2: Calculate C contribution

$6 \times 12 = 72\ \text{g/mol}$

Step3: Calculate H contribution

$12 \times 1 = 12\ \text{g/mol}$

Step4: Calculate O contribution

$6 \times 16 = 96\ \text{g/mol}$

Step5: Sum all contributions

$72 + 12 + 96 = 180\ \text{g/mol}$

Answer:

b) 180,g/mol
