There is 1 OH- in 1 molecule of NaOH.
Also, there is 1 H+ in 1 molecule of lactic acid.
So the reaction is simple.
so just equate the moles
moles of OH- in NaOH = moles of H+ in lactic acid
26.8 x 0.07 = 250 x Mole of lactic
Moles of lactic = 0.0075
so mass = 0.0075 x 90.8 = 0.681 g

Explanation:
the 4 by the element symbol O multiplied by the 3 on the outside of the parentheses
Answer:
This list of electron configurations of elements contains all the elements in increasing order of atomic number.
To save room, the configurations are in noble gas shorthand. This means part of the electron configuration has been replaced with the element symbol of the noble gas symbol. Look up the electronic configuration of that noble gas and include that value before the rest of the configuration.

CATGGATCCA for future reference this is considered biology, you may get a quicker response if you categorize it as such :)
