How many millilitres of a 9.0 mol L^-1 H₂SO₄ solution are needed to make 0. 35 L of a 3.5 mol L^-1 solution?

Question

Quizplus · Accepted Answer

Use the equation: M1V1 = M2V2 where: M1 = 9.0 mol L^-1 H₂SO₄ V1 = unknown (what we're solving for) M2 = 3.5 mol L^-1 V2 = 0.35 L Rearranging the equation gives: V1 = (M2V2) / M1 Plugging in the values: V1 = (3.5 mol/L * 0.35 L) / 9.0 mol L^-1 H₂SO₄ V1 = 0.1361 L Convert to mL: V1 = 0.1361 L * 1000 mL/L = 136.1 mL Round to the nearest whole number and the answer is C) 140 mL.
