Answer to Question #133638 in General Chemistry for Mike

Question

How much moles of the carbon exist in 0,15 mol sucrose (answer required in moles)?

Answer 1

Formular for sucrose$=C_{{_1}{_2}}H_{{_2}{_2}}O_{{_1}{_1}}$

The molar mass of sucrose $= 342.3g/mol$

From the formula, $1$ mole of Sucrose$=$ $12$ moles of Carbon.

$1$ mole of Sucrose represents $6.022\times 10^{23}$ Atoms of Sucrose(Avogadro number)

$\therefore$ If $1$ mole of Sucrose$= 12$ moles of Carbon.

Then $0.15$ moles of Sucrose

$=$ $0.15 Moles \times 12 Moles \over 1 Mole$

$=1.8 mol C$
