Answer:

Approx. #75*g#.

Explanation:

We use the quotient.....#"Concentration"="Moles of solute (mol)"/"Volume of solution (L)"=("Mass of solute"/"Molar mass of solute")/"Volume of solution"#, and clearly it has the units required units of #mol*L^-1#.

And thus..................

#"concentration"xx"volume"xx"molar mass of solute"="mass of solute"#. With me?

#"Mass of solute"=0.50*mol*L^-1xx2*Lxx74.55*g*mol^-1=??*g#.

Should you be able to do this as mental arithmetic?
