Question

Calculate the molar mass of sucrose:

Answer 1

342 g.

Step-by-step explanation:

• C12H22O11 ------> Sugar

Carbon has mass -> 12

Hydrogen has mass -> 1

Oxygen has mass -> 16

=> (12× 12 ) + (1 ×22 ) + ( 16 × 11 )

=> 144 + 22 + 176

=> 342 gram

__________________

• Molecular mass : The Molecular mass of a substance is the sum of the atomic masses of all atoms in a molecule of a substance, e.g ., Molecular mass of water is 18u.
• H2O = 2 × H + 1 × O
• => 2 × 1 + 1 ×16 = 2+16
• = 18 u.
• Mass of one mole of a substance is called its molar mass.

what is a Molecule?

• A Molecule is the smallest Particle of an element or a compound capable of independent existence under ordinary conditions. It shows all the properties of tge substance.

Answer 2

342 g/mole

Step-by-step explanation:

Mass of the carbon = 12 g

Mass of the hydrogen = 1 g

Mass of the oxygen = 16 g

Given: Chemical Formula of the Sucrose = C12H22O11

Molar mass = 12 x 12 + 1 x 22 + 16 x 11

= 144 + 22 + 176

= 320 + 22

= 342 g/mole ➪ molar mass of the sucrose
