We are asked to choose a method to produce 0.200 M K_{2}SO_{4}

Recall dilution equation:

$\overline{){{\mathbf{M}}}_{{\mathbf{1}}}{{\mathbf{V}}}_{{\mathbf{1}}}{\mathbf{}}{\mathbf{=}}{\mathbf{}}{{\mathbf{M}}}_{{\mathbf{2}}}{{\mathbf{V}}}_{{\mathbf{2}}}}$

A 0.200 M K_{2}SO_{4} solution is produced by _____.

A) dilution of 250.0 mL of 1.00 M K_{2}SO_{4} to 1.00 L

B) dissolving 43.6 g of K_{2}SO_{4} in water and diluting to a total volume of 250.0 mL

C) diluting 20.0 mL of 5.00 M K_{2}SO_{4} solution to 500.0 mL

D) dissolving 20.2 g of K_{2}SO_{4} in water and diluting to 250.0 mL, then diluting 25.0 mL of this solution to a total volume of 500.0 mL

E) dilution of 1.00 mL of 250 M K_{2}SO_{3} to 1.00 L
