Choose the best answer:

Sarah prepared two sugar solutions using different masses of sugar. To compare their concentrations, she used the mass by mass percentage formula. What is the correct formula for calculating mass by mass percentage?

\(\text{Mass by mass percentage}\) \(=\) \(\frac{\text{Volume of solute}}{\text{Volume of solution}}\)\(\times100\)
\(\text{Mass by mass percentage}\) \(=\) \(\frac{\text{Mass of solution}}{\text{Mass of solue}}\)\(\times100\)
\(\text{Mass by mass percentage}\) \(=\) \(\frac{\text{Mass of solute}}{\text{Volume of solution}}\)\(\times100\)
\(\text{Mass by mass percentage}\) \(=\) \(\frac{\text{Mass of solute}}{\text{Mass of solution}}\)\(\times100\)
