Answer:
320 mmol
Explanation:
405.0 mL * 1L/1000 mL = 0.4050 L
0.79 M = 0.79 mol/L
0.79 mol/L * 0.4050 L=0.32 mol
0.32 mol * 10^3 mmol/1 mol = 320 mmol
is the of
is in 405,576.398 mL.

What is molarity?</h3>
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
= 0.762 mol
Volume of solution = 405,576.398 mL = 405,576.398 mL/1000 = 405.576398 L
Solution:
Step 1: Calculating moles of 
• Molarity =
• Putting the value in the given formula
• Moles of solute C8H18 = 
• Moles of solute C8H18 = 
Now,
Molarity =
Molarity =
Molarity =

Hence,
is the of
is in 405,576.398 mL.

CH3NH2 can only have as many hydrogen bonds as hydrogen bonding sites in the molecule. CH3NH2 has two N−H bonds and a lone pair of electrons on the nitrogen atom. Therefore, CH3NH2 can form three hydrogen bonds with water.
