Question below:
A solution containing 5 mL of each 4 M acetone, 1 M HCl, and 0.005M iodine is mixed with 10 mL of water. What is the molarity of acetone in the reaction mixture? How could you double the molarity of acetone in the reaction mixture, using the solutions above, and keeping the total volume the same (25 mL)?
Two aqueous sulfuric acid (H2SO4) solutions containing 20.0 wt% H2SO4 (SG=1.139) and 80.0 wt% H2SO4 (SG=1.727)...
Two aqueous sulfuric acid (H2SO4) solutions containing 20.0 wt% H2SO4 (SG=1.139) and 80.0 wt% H2SO4 (SG=1.727) respectively, are mixed to form a 4.00 molar solution (mol/L) (SG=1.213). Calculate the mass fraction of sulfuric acid in the product stream. Atomic weight: H=1g/mol, O=16g/mol, S=32g/mol. Taking 100 kg of the 20 wt% feed solution as a basis, calculate the volumetric feed ratio of 20.0 wt% H2SO4 to 80.0 wt% H2SO4, to 2 decimal places.

Two 1-L beakers, A and B, each containing a different aqueous solution of urea (a nonvolatile nonelectrolyte with MW = 60.06 g/mol) are placed together in a box, which is then sealed. The temperature remains constant at 20 °C. Initially, there is 270 mL of solution in A and 690 mL of solution in B. As the solutions stand in the sealed box, their volumes change slowly for a while. When they stop changing, beaker A contains 490 mL and...
