What type of bond is H2Se

1 answer:

6 0

Answer:The lone pair of electrons takes up more space than a regular bonding pair since it it is not confined to be between two atoms, so it adds coulombic repulsion to the bonding pairs and compresses the angle. Therefore, the bond angle is less than the standard 109.5∘ . It is actually 97.7∘

How many grams of C8H18<br> is in 405,576.398 mL

nevsk [136]

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

<h3>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 $C_8H_1_8$ = 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 = $\frac{\;Moles \;of \;solute}{\;Volume \;of \;solution \;in \;litre}$
