What is the molecular mass of glucose molecule up to 6 significant figures?
What is the molecular mass of glucose \( C_{6} H_{12} O_{6} \) molecule up to 6 significant figures?
- A. 0180.16
- B. 180.16
- C. 180.1620
- D. 180.162
Step-by-step solution
Using atomic masses: C=12.011, H=1.008, O=16.00 (common approximation), the molecular mass is 6*12.011 + 12*1.008 + 6*16.00 = 72.066 + 12.096 + 96.00 = 180.162. This is accurate to 6 significant figures.
