Question

calculate mass of 1 molecule of glucose​

Answer 1

Explanation:

C6H12O6 = 72.06 × 100 % = 40.0 % by mass. 180.18 Similarly, the percentage of hydrogen and oxygen can be calculated as follows: 1 mole of H atoms weighs 1.01 g and there are 12 moles of H atoms in 1 mole of glucose, so the mass of hydrogen in 1 mole of glucose = 12 × 1.01 g = 12.12 g.

Answer 2

Thus, the mass of 1 molecule of glucose is $29.88×10^{-23}$grams.

Given:

1 molecule of glucose.

To find:

The mass.

Solution:

We know that the molecular mass of glucose is 180 grams/mol.

We can write-

$6.023×10^{23}$ number of molecules of glucose occupy 180 grams of glucose.

Thus 1 molecule of glucose occupies $180/6.023×10^{23}=29.88×10^{-23}$grams of glucose.

Thus, the mass of 1 molecules of glucose is $29.88×10^{-23}$grams.
