Answer to Question #154416 in Chemistry for Sara Annan

Question #154416

A solution S of sulfuric acid is prepared by dissolving 49g of H2SO4 in 500 mL of distilled water. Calculate the molar concentration of the solution

Expert's answer

C_M=n/V

n=m/M

M(H₂SO₄)=98 g/mol

n(H₂SO₄)=49/98=0.5 mol

V=500 ml = 0.5 l

C_M=0.5/0.5=1 mol/l
