Answer:
Explanation:
We're asked to find the molarity of the
First, let's write the balanced chemical equation for this neutralization reaction:
 Here's a hint we can use only in the special case of onetoone molar ratios:
where

#M_1# and#M_2# are the molarities of the two solutions 
#V_1# and#V_2# are the volumes of the two solutions
We have:

#M_1 = 0.0249M# (#"NaOH"# ) 
#V_1 = 28.7# #"mL"# 
#M_2 = ?# (#"HCl"# ) 
#V_2 = 25.00# #"mL"#
Plugging in known values, we have
