Explanation / Answer

a) A type beaker as it is having better graduations

b) Measure out x gms of solid sucrose on a beaker

c) As Molarity = moles of solute/ volume of solution

   moles of sucrose = 0.1*250ml /1000ml = 0.025 moles

mass of sucrose = moles *molar mass= 0.025 *342.3 = 8.5575g = 8.56g =X g

d) Fill the container with water to the 250 ml mark, then add the solute.
