Question

Using stoichiometry, determine the mass of powdered drink mix needed to make a 1.0 M solution of 100 mL from C12H22O11

Answer 1

Answer:

34.23 g.

Explanation:

Molarity is defined as the no. of moles of a solute per 1.0 L of the solution.

M = (no. of moles of solute)/(V of the solution (L)).

∴ M = (mass/molar mass)of C₁₂H₂₂O₁₁/(V of the solution (L)).

∴ mass of C₁₂H₂₂O₁₁ = (M)(molar mass)(V of the solution (L) = (1.0 M)((342.3 g/mol)/(0.10 L) = 34.23 g.
