A chemist starts with 73mL of a 0.3M NaCl solution and dilutes it to 677mL. What is the Molar concentration of NaCl in the new solution? • Answer to 3 decimal places • Read about significant figures and rounding in the Helpful Resources page! • Do not include units when reporting your answer • Use standard notation or scientific notation as accepted by blackboard • e.g. 0.001 or 15-3, not 1 x 10^-3
An analytical chemist is titrating 201.8 mL of a 0.5300 M solution of nitrous acid (HNO, with a 1.100 M solution of KOH. The pk of nitrous acid is 3.35. Calculate the pH of the acid solution after the chemist has added 116.5 mL of the KOH solution to it. Note for advanced students: you may assume the final volume equals the initial volume of the solution plus the volume of KOH solution added. Round your answer to 2 decimal...
