Hey there !:
Molarity is the amount of solute, in mol, dissolved in a volume of solution in Liters , so:
Moles of solute = 0.50 mol
Volume of solution = 6.50 L
Therefore:
Molarity = moles of solute / volume of solution
Molarity = 0.50 / 6.50
Molarity = 0.0769 M
Hope that helps!
Answer:
Option (b) 0.67 M
Explanation:
The following Data were obtained from the question:
Mole of MgCl2 = 0.5 mole
Volume of solution = 750mL
Molarity of MgCl2 =?
Next, we shall convert the volume given from mL to L. This is illustrated below:
1000mL = 1L
Therefore 750mL = 750/1000 = 0.75L
Now we can obtain the molarity of MgCl2 as follow:
Molarity is defined as the mole of solute per unit litre of the solution i.e
Molarity = mole /Volume
Molarity = 0.5/0.75
Molarity of MgCl2 = 0.67 M
The Bohr Model, which was proposed by Niels Bohr in 1913
Not strong base and acid, not dissolved or not aqueous.
