Question

156 g C12H22O11 (sucrose) is dissolved into 4.0 L of solution. What is the molar concentration of the solution? Report your answer with the correct number of significant figures.

Answer 1

Answer:

The molar concentration is 0.114 M (≈0.11 M)

Explanation:

Step 1: Data given

Mass of sucrose = 156 grams

Molar mass of sucrose = 342.3 g/mol

Volume = 4.0 L

Step 2: Calculate moles sucrose

Moles sucrose = mass sucrose / molar mass sucrose

Moles sucrose = 156 grams / 342.3 g/mol

Moles sucrose = 0.456 moles

Step 3: Calculate molar concentration of the solution

Concentration of solution = moles sucrose / volume

Concentration of solution = 0.456 moles / 4.0 L

Concentration of solution = 0.114 M

The molar concentration is 0.114 M (≈0.11 M)
