Answer 2

Chemical Formula of Sugar

The chemical formula of sugar can be determined based on the given composition of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.

Sugar is a generic term that can refer to different types of sugars, such as glucose, fructose, or sucrose. However, based on the given composition, we can assume that the sugar in question is glucose.

The chemical formula of glucose is C6H12O6. It consists of 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

Relative Molecular Mass of Sugar

To calculate the relative molecular mass of sugar (glucose), we need to consider the atomic masses of carbon, hydrogen, and oxygen.

The atomic mass of carbon (C) is approximately 12.01 atomic mass units (amu), the atomic mass of hydrogen (H) is approximately 1.008 amu, and the atomic mass of oxygen (O) is approximately 16.00 amu.

Using these atomic masses, we can calculate the relative molecular mass of glucose (C6H12O6) as follows:

(6 * 12.01 amu) + (12 * 1.008 amu) + (6 * 16.00 amu) = 72.06 amu + 12.096 amu + 96.00 amu = 180.156 amu

Therefore, the relative molecular mass of sugar (glucose) is approximately 180.156 amu.

Please note that the given composition and calculations are based on the assumption that the sugar in question is glucose. Different types of sugars may have different chemical formulas and molecular masses.
