Problem 75E Complete and balance each equation. If no reaction occurs, write “NO REACTION.” Step-by-Step Solution:
Step 1 of 3

Solution: Here, we are going to describe a process to prepare 250 mL of a 0.250 M sucrose solution. Also, we are going to describe a process to prepare 350.0 ml of 0.100 M sucrose solution starting with 3.00 L of 1.50 M sucrose solution. Step1: Molarity is defined as the number of moles of the solute(Here sucrose is the solute) in 1 litre of the solution. Mathematically, Number of moles of solute Molarity(M) = -------------------------------------- ------(1) Volume of solution in litres Step2: a) Given, volume of the sucrose solution = 250 mL = 250 / 1000 L = 0.250 L Molarity of the sucrose solution = 0.250 M Now, using the molarity expression, we get, Number of moles of sucrose(C H O ) = v12m22f 11ution in litres X Molarity C12H22O11 = 0.250 X 0.250 M = 0.0625 mol Now, 1 mole of C H O 12o22 m11 of C H O 12 22 11 Therefore, 0.0625 moles of C H O = 0.0625 X molar mass of C H O 12 22 11 12 22 11 = 0.0625 X 342.3 g [molar mass of C12 O22 11.3 g/mol] = 21.39 g So, to prepare 250 ml of a 0.250 M sucrose solution, we have to dissolve 21.39 g...
