Question

The total number of electrons in 1 kg glucose ( C6H12O4) is { molecular mass of glucose is 180 u }

Answer 1

Molecular mass : The sum of the atomic masses of all the atoms in a molecule of a substance is called the molecular mass of the molecule.
Generally we use relative atomic masses of atoms for calculating the molecular mass of 1 mole of any molecular or ionic substances.
Molecular formula of glucose is C6H12O6
Atomic mass of H = 1
Atomic mass pf C = 12
Atomic mass of O = 16
Molecular mass of C6H12O6 = 12(Atomic mass of Hydrogen) + 6(Atomic mass of carbon) + 6(Atomic mass of oxygen)
= 12 x 1 + 6X12 + 6X16
= 12 + 72 + 96 = 180 u.

Answer 2

Answer:

Molecular mass : The sum of the atomic masses of all the atoms in a molecule of a substance is called the molecular mass of the molecule.

Generally we use relative atomic masses of atoms for calculating the molecular mass of 1 mole of any molecular or ionic substances.

Molecular formula of glucose is C6H12O6

Atomic mass of H = 1

Atomic mass pf C = 12

Atomic mass of O = 16

Molecular mass of C6H12O6 = 12(Atomic mass of Hydrogen) + 6(Atomic mass of carbon) + 6(Atomic mass of oxygen)

= 12 x 1 + 6X12 + 6X16

= 12 + 72 + 96 = 180 u.
