You are given powdered sodium sulfate, how will you prepare 100 mL of a 1M solution of sodium sulfate? Your solvent is 0.1 M acetate buffer.
Homework Answers
Na2SO4 is the formula of sodium sulfate.
molar mass of sodium sulfate is (2*23)+32+(4*16)=142 g/mol.
molarity is the no. of moles per liter of solutions.
and 142 g of sodium sulfate means 1 moles sodium sulfate. 1 M( molarity) of sodium sulfate means 1 mole of sodium sulfate dissolve in 1 liter of solution.
1000 mL of solution dissolve 142 g of sodium sulfate to form 1 M of sodium sulfate
then 1 mL of solution dissolve 142/1000 g of sodium sulfate to form 1 M of sodium sulfate
100 mL of solution will dissolve 142*100/1000 g of sodium sulfate to form 1 M of sodium sulfate.
=14.2 g of sodium sulfate form 1 M of sodium sulfate.

Pour 2.5 mL of the 1M glucose (C6H12O6) solution from the flask into the 100 mL volumetric flask. Use the “dilution equation” to determine the volume in mL for the required 0.025M solution, given that the original solution is 1M and you used 2.5 mL Fill the volumetric flask to the 100 mL mark with distilled water. Note: The flask already contains a volume of 2.5 mL. 1. Compute the volume of the diluted 0.025 M solution. 2. What volume...
