Answer:

Well.....#1.45*mL#

Explanation:

We take the quotient........

#(50*cancel"mEq")/(35*cancel"mEq"*"mL"^-1)=1.43*1/(1/("mL"))=1.43*"mL"...#

I think this is a chemically unreasonable concentration. Conc. #HCl# as used in the lab is approx. #10*mol*L^-1# and is #38-40%# #w/w#.

I would not want to handle hydrochloric acid of this concentration.
