Answer:
[tex]0.0438\text{ mole}[/tex]Explanation:
Here, we want to calculate the number of moles of sucrose in the mass of the sample
Mathematically, we have that as:
[tex]\begin{gathered} Number\text{ of moles = }\frac{mass}{molar\text{ mass}} \\ \end{gathered}[/tex]The mass given is 15g, and the molar mass is 342.3 g/mol
Thus, we have the number of moles as:
[tex]Number\text{ of moles = }\frac{15}{342.3}\text{ = 0.0438 mole}[/tex]
