Question

Calculate solution concentration in molarity units. A student weighs out 21.3 g of $K_2SO_4$, transfers it to a 500. ml volumetric flask, adds enough water to dissolve the solid and then adds water to the 500 mL mark on the neck of the flask. Calculate the concentration (in molarity units) of potassium sulfate in the resulting solution?

Step 1

3 g sample. To do this, we need to know the molar mass of K2SO4. The molar mass of K is 39.10 g/mol, the molar mass of S is 32.07 g/mol, and the molar mass of O is 16.00 g/mol. The molar mass of K2SO4 is: (2 * 39.10 g/mol) + 32.07 g/mol + (4 * 16.00 g/mol) = Show more…
