Final answer:
To calculate the number of sucrose molecules in 14.3 ml, the concentration of the sucrose solution is required. Once the concentration is known, moles can be calculated and then converted to molecules using Avogadro's number.
Step-by-step explanation:
To determine how many molecules of sucrose are contained in 14.3 ml, we need more information than what is provided. Specifically, we need the concentration of the sucrose solution (molarity), which is measured in moles per liter (M). Once we know the concentration, we can use the formula:
Number of moles = Volume (L) × Concentration (M)
After determining the number of moles, we can then convert moles to molecules using Avogadro's number (6.022 × 1023 molecules/mole):
Number of molecules = Number of moles × Avogadro's number
Unfortunately, without the concentration of the sucrose solution, we cannot calculate the number of sucrose molecules in 14.3 ml.
