Question

How many C₆H₁₂O₆ molecules are contained in a 100g sample of C₆H₁₂O₆

Answer 1

Molar mass of $C_6H_{12}O_6=180.15588g$

Avogadro's constant $=6.0221409×10^{23}$

Moles of $C_6H_{12}O_6=\frac{100}{180.15588}$

Number of molecules $=\frac{100}{180.15588}×6.0221409×10^{23}$

$=3.3427×10^{23}$ Molecules
