Question

How many grams of C8H18 is in 405,576.398 mL

Answer 1

$Molarity X \frac{0.762 mol}{05.576398 L} = Mass$ is the of $C_8H_1_8$ is in 405,576.398 mL.

What is molarity?

Molarity (M) is the amount of a substance in a certain volume of solution. Molarity is defined as the moles of a solute per litres of a solution. Molarity is also known as the molar concentration of a solution.

Given data:

Molar mass of  $C_8H_1_8$ = 0.762 mol

Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L

Solution:

Step 1: Calculating  moles of $C_8H_1_8$

• Molarity =$\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}$

• Putting the value in the given formula

• Moles of solute C8H18 = $\frac{\;Mass}{\;Molar \;molar \;mass}$

• Moles of solute C8H18 = $\frac{\;Mass}{0.762 mol}$

Now,

Molarity =$\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}$

Molarity =$\frac{\frac{\;Mass}{0.762 mol}}{\;Volume \;of \;solution \;in \;litre}$

Molarity =$\frac{\frac{\;Mass}{0.762 mol}}{405.576398 L}$

$Molarity X \frac{0.762 mol}{05.576398 L} = Mass$

Hence, $Molarity X \frac{0.762 mol}{05.576398 L} = Mass$ is the of $C_8H_1_8$ is in 405,576.398 mL.
