Question

calculate the number of hydrogen atom in 90g of glucose.​

Answer 1

90g of Glucose contains  6505 * $10^{23}$  atoms of Hydrogen.

Given:

90g of Glucose

To find:

Number of hydrogen atoms in 90g of glucose

Solution:

Glucose, also known as dextrose, is a type of carbohydrate known as a simple sugar (monosaccharides). The molecular formula for glucose is C6H12O6. It is found in fruits and honey and is the most abundant free sugar in the blood of higher animals. It is the source of energy in cell function, so controlling its metabolism is critical (see fermentation; gluconeogenesis). Starch molecules, the primary energy-reserve carbohydrate in plants, are made up of thousands of linear glucose units. Another major glucose compound that is also linear is cellulose. D-glucose is the molecule Dextrose.

Molecular formula of glucose- C6H12O6

This means, one molecule of glucose contains 12 atoms of Hydrogen.

1 mole of glucose weights 180 g, which contains 6.023 ×$10^{23}$  molecules of glucose.

So, 0.9 g of glucose contains 6.023×$10^{23}$ molecules of glucose which means it contains

⇒ (6.023×$10^{23}$) × 12 X 90

⇒ 6.023*$10^{23}$*1080

⇒ 6505 * $10^{23}$

Therefore, 90g of Glucose contains  6505 * $10^{23}$  atoms of Hydrogen.
