average concentration = .8509 M average density = .9987 g/mL molar mass = 60.05 g/mol

First write a balanced equation.

Remember that Molarity is moles over liters of solution.

the balanced equation is\[C _{2}H _{4}O _{2}+NaOH \rightarrow C _{2}H _{3}O _{2}Na+ H _{2}O\]

@Photon336 well this is from an acid-base titration lab i did recently. what other info do i need? the question says to use the average concentration and density and the molar mass of acetic acid. i could show you how i did it but i feel like its not right.
