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?
