1 Answer

Dec 12, 2016

Approx. #6*g# of salt.

Explanation:

#"Concentration"# #=# #"Moles of solute"/"Volume of solution"#

And thus, #"moles of solute"="concentration"xx"volume of solution"#.

So, #"moles"# #=# #350xx10^-3*Lxx0.287*mol*L^-1=0.100*mol#.

And #"mass of salt"# #=# #0.100*molxx58.44*g*mol=??g#
