We know the concentration can be considered as the term of molarity.
Molarity can be defined as the number of moles of solute present in a liter of solution.
Mathematical Expression

w= given mass
MM= molar mass
v= volume in mL
Here in the given question the molecule is
.
MM= 233.99 gm/mol
v= 500 mL
w= 35.0 g
Now apply the molarity equation


Hence the concentration is 0.3 M or 0.3 moles/liter
