Mass is the measure of the quantity of the substance present in the sample containing a compound or molecule. The mass of sucrose in the sample is 171 g.
The mass of the compound in the sample is the product of the number of moles of the substance and the molar mass of the compound.
Given,
The molar mass of the sucrose compound = 342.3 g/mol
Number of moles of sucrose = 0.500 moles
Mass of sucrose is calculated as:
[tex]\begin{aligned}\rm mass &= \rm moles \times molar \; mass\\\\&= 0.500 \;\rm moles \times 342.3 \;\rm g/mol\\\\&= 171.15 \;\rm gm\end{aligned}[/tex]
Therefore, option A. 171 gm is the mass of sucrose.
