What is the %v/v of a solution made from 186.1 g of ethylene glycol (density is 1.11 g/mL) in water (density 1.00 g/mL) to form a total volume of 500.0 mL? You may assume the density of ethylene glycol does not change in the solution.
a What mass (in grams) of sodium sulfate, Na₂SO4, is needed? Mass= 24.85 mNa₂SO4 You know the volume (5.00 x 102 mL) and molarity (0.35 M). The molar mass of Na2SO4 is 142 g/mol. To calculate the mass of sodium sulfate multiply the volume of solution by the molarity to convert it to moles; then convert to mass of solute by multiplying by the molar mass: 1 L 5.00 x 102 mL x 1000 mL g 1 X 0.35 mol Na2SO4 1 L soln Submit Correct X 142 g Na₂SO4 1 mol Na₂SO4 25 g b Describe how would you prepare this solution. Take 500-ml volumetric flask and add water to fill the flask to the mark on the neck. Then weigh out 25 g of pure Na2SO4 and place it in the flask. Mix well by inverting the stoppered flask several times. Weigh out 25 g of pure Na2SO4, and place it in a 300-mL volumetric flask. Add some water to fill roughly half of the flask to dissolve the solid with swirling. Then add enough water to fill the flask to the mark on the neck and mix well by inverting the stoppered flask several times.…
