Answer:
Explanation:
The difference between bond pair & lone pair is that a bond pair is composed of two electrons that are in a bond . a lone pair is composed of two electrons that are not in a bond.
The answer is A because The fact of temperature on volume changes of substance.
6,02·10²³ --- 1 mol
X -------------- 6,5 mol
X = 6,02·10²³×6,5
X = 39,13·10²³ molecules of Cl₂
Answer:
1.25 M
Explanation:
Step 1: Given data
Mass of KI (solute): 20.68 g
Volume of the solution: 100 mL (0.100 L)
Step 2: Calculate the moles of solute
The molar mass of KI is 166.00 g/mol.
20.68 g × 1 mol/166.00 g = 0.1246 mol
Step 3: Calculate the molar concentration of KI
Molarity is equal to the moles of solute divided by the liters of solution.
M = 0.1246 mol/0.100 L= 1.25 M
