1. In a titration, 33.21 mL 0.3020M rubidium hydroxide solution is required to exactly neutralize 20.00 mL hydrofluroic acid solution. What is the molarity of the hydrofluroic acid solution?
Answer: 0.502HF
2. A 35.00 mLsample of NaOH solution is titrated to an endpoint by 14.76 mL 0.4122M HBr solution. What is the molarity of the NaOH solution.
Answer: 0.174M NaOH

Why did you throw away some of the answer?
You have 4 places in each of these problems but you rounded your answer to 3. You threw away a perfectly good number in each problem. Otherwise, both look ok to me. 
what is the molarity of a solution prepared by diluting 500ml of a 6.0 M solution to 750 ml?

how would you prepare 60.0 ml of 0.2 M HNO3 from a stock solution of 4.00 M HNO3?
