Question

Calculate the RMM of glucose given that the emperical formular is
Ch2o

Answer 1

The RMM of glucose (C6H12O6) is calculated by adding the atomic weights of its constituent atoms, resulting in an RMM of 180.156 u.

Step-by-step explanation:

We can calculate the relative molecular mass (RMM) of glucose by using its molecular formula, which is C6H12O6. The RMM is the sum of the atomic weights of each atom in the molecule. Carbon (C) has an atomic weight of 12.01, Hydrogen (H) is 1.008, and Oxygen (O) is 16.00 on the periodic table. So for glucose:

• Carbon: 6 atoms × 12.01 = 72.06
• Hydrogen: 12 atoms × 1.008 = 12.096
• Oxygen: 6 atoms × 16.00 = 96.00

Adding these together, the RMM of glucose is 72.06 + 12.096 + 96.00 = 180.156 u (atomic mass units).
