Question

Calculate the molar mass of Sucrose (C12H22O11).

Answer 1

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 × 12 + 1 × 22 + 16 × 11
= 144 + 22 + 176
= 320 + 22
= 342 g/mole.


Hence the Molar mass of the Sucrose is equals to 342 g/mole.


Hope it helps.

Answer 2

The total molecular mass of sucrose is 342 g/mole.

Chemical Formula of the Sucrose = $C_{12}H_{22}O{11}$

The atomic number of the atoms present in Sucrose are:

Carbon = 12

Hydrogen = 1

Oxygen = 16

∴, the total molecular mass of sucrose is = 12 × 12 + 1 × 22 + 16 × 11

                                                                    = 144 + 22 + 176

                                                                    = 320 + 22

                                                                     = 342 g/mole.
