Question

now that you know that 50.5 grams of sucrose is equal to 0.147 moles of sucrose, we need to use this information to find the molarity (the unit of measuring concentration). we can calculate the molarity (m) or concentration of a solution in moles / l if we know the volume of the solution in liters (l). lets say you mixed your 0.147 moles of sucrose into 0.0012 l of solution. report your answer to 2 significant figures. solute: 0.147 moles sucrose solution: 0.0012 l solution what is the molarity of this solution? molarity (m) = molles of solute / liters of solution molarity is the amount of moles of a substance dissolved in a liter of solution (usually an aqueous or water - based solution).

Explanation:

Step1: Use the molarity formula

Molarity \( M=\frac{\text{moles of solute}}{\text{liters of solution}} \). Here, moles of solute \( n = 0.147\) mol and liters of solution \( V=0.0012\) L.

Step2: Substitute the values into the formula

\( M=\frac{0.147}{0.0012}\)

Step3: Round to 2 significant figures

\(122.5\approx1.2\times10^{2}\)

Answer:

\(1.2\times 10^{2}\text{ M}\)
