Question

how many sucrose molecules are in 3.0 moles of sucrose

Answer 1

Given:

Number of moles of sucrose = 3.0

To find:

Number of sucrose molecules = ?

Calculation:

1 mole of sucrose is composed of $6.02\times10^{23}$ molecules.

∴ 3.0 Moles of sucrose contains =  3.0 × $\frac{6.02\times10^{23}}{1}$ = 3.0× $6.02\times10^{23}$

3.0 Moles of sucrose contains = 1.80×$10^{24}$ molecules.

Conclusion:

Thus it can be inferred that 3.0 moles of sucrose is composed of 1.08×$10^{24}$ molecules.
