Expert Solution

Step 1

Hii there, since there are multiple questions posted. we are answering first question. if you need further questions to be answered please submit the question with specific question number.

Given:

Initial Volume = 250.0 mL

Initial molarity = 15.67 M

Initial density = 1.7872 g/mL

Volume pipetted out = 70.0 mL

Final volume after dilution = 500.0 mL

Final density = 1.1318 g/mL
