a solution is prepared by mixing 1.0 grams of benzen(c6h6) in 100g of water to create a solution total volume of 100ml.calculate the molarity,mass percent,mole fraction and molarity of benzene in the solution
C6H6 --> 6*12 + 6 = 78 grams/mol
so we have 1/78 mol
1/78 mol in 0.1 liter --> 10/78 molarity etc
