Enter the number only (no units) • Do not leave any spaces • Include the sign if your answer is negative (not necessary for positive values) • Use a leading zero before the decimal when necessary • Report your number to 2 decimal places (regardless of the significant figures) • Correctly round your answer to the 2nd decimal place (margin of allowed error is only + 0.01, so always use un-rounded numbers in your calculations). If the last digits are zeros they will not display once you click away, but the answer will still be marked correct. Examples: 12.34 or -0.56 a) If there are 0.150 moles NH4* and 0.250 moles NH3 in 0.1000 L of the buffer, then what is the initial pH of the buffer? pH initial b) If 0.090 moles HCl in 0.0100 L of solution is added to the 0.1000 L of buffer, what is the final pH of the new solution? pH final c) What is the change in pH?
