Answer:

#"Concentration"="Moles of stuff"/"Volume of solvent"............#

Explanation:

And #"mass of stuff"="molar mass"xx"moles of stuff"#

So....................

#"mass"="molar mass"xx"moles of stuff"xx"volume"xx"concentration"#.

#=105.99*g*cancel(mol^-1)xx0.25*cancel(mol)xx0.250*cancelLxx0.25*cancel(mol)*cancel(L^-1)#

#="a little under 2 grams"..............#
