Question

A solution is prepared by mixing 9.99 grams of benzene (C6H6) in water to create a solution total volume of 100 ml. Calculate the molarity of the solution

Answer 1

Answer:

[C₆H₆] = 1.28 M

Explanation:

Let's determine the molar mass of benzene

Molar mass of benzene = 12g/m .6 + 6 . 1g/m = 78 g/m

Mol = mass / molar mass

9.99 g / 78 g/m = 0.128 mol

Molarity = mol/L

0.128 mol / 0.1 L = 1.28 M
