Question

calculate the molecular mass of glucose molecule

Answer 1

glucose = C6H12O6

molecular mass = 6(12) + 12(1) + 6(16)
= 72 + 12 + 96

= 180 g

Answer 2

180g will be the molecular mass of the glucose molecule.

Explanation:

As per the chemical formula of glucose, we know that it contains 6 carbons, 12 hydrogens, and 6 atoms of oxygen.

Using the periodic table, the atomic weights of C, H, and O would be 6(12), 12(1), and 6(16) respectively.

Thus, the molar mass of glucose would be:

⇒ 6 x 12 + 1 x 12 + 6 x 16

⇒ 72 + 12 + 96

= 180g
