You have prepared a buffer by combining 5.00 ml 0.010 m ha (weak acid) and 3.00 ml 0.010 m naa (provides a -, the conjugate base of ha). pk a for ha is 6.23. how many moles of a - will be present in the mixture after addition of 0.20 ml 0.010 m naoh? (suggestion: start by calculating the moles of everything in the mixture.) enter the numerical value, without units, to at least 2 significant figures. you may use e-format scientific notation, e. g., 1.23x10 -4 would be entered as 1.23e-4. (note that the acid and base do not add up to 20.00 ml -- water must be added. that does not affect how you answer the question.)
