Type the correct answer in the box. Isopropanol (C3H8O) is a key ingredient in some hand sanitizers. Suppose that 127 grams of isopropanol is dissolved in water. The volume of the solution is 1,250 milliliters. What is the molarity of the solution? Refer to the periodic table to help you answer. Express your answer to three significant figures. The molarity of the solution is M.

Respuesta :

The molarity of the Isopropanol solution is 1.68 M.

How we calculate molarity?

Molarity of any solution can be calculated as:

M = n/V, where

n = no. of moles

V = volume = 1,250mL = 1.250L

For this first we have to calculate the moles of Isopropanol (C₃H₈O), and it can be calculated as:

n = W/M, where

W = mass of C₃H₈O = 127 grams

M = molar mass of C₃H₈O = 60.1 g/mol

Moles of C₃H₈O = 127g / 60.1 g/mol = 2.1 moles

Now, we calculate the molarity of solution by using the above formula and by putting values as:

M = 2.1/1.250 = 1.68 M

Hence, 1.68 M is the molarity of the solution.
