Answer:

#"Option b"#

Explanation:

#"Molarity"# #=# #"Moles of solute"/"Volume of solution"#, and so we work out the quotient.....

#((117*g)/(58.44*g*mol^-1))/(1*L)=???*mol*L^-1#.

The initial dilution was there to distract you. We only need the final volume, and the amount of solute dissolved INITIALLY.
