8.59 is the concentration of ethyl alcohol when 0.198 kg of ethyl alcohol.
Define the molarity of a solution.
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:
Volume of solution = 0.500 L
Given the mass of [tex]C_2H_5OH[/tex]= 0.198 kg= 198g
Molar mass of [tex]C_2H_5OH[/tex] = 46.07 g/mol
Moles of [tex]C_2H_5OH[/tex] = 4.297807684
[tex]Molality = \frac{Moles \;solute}{Volume \;of \;solution \;in \;litre}[/tex]
[tex]Molality = \frac{4.297807684}{0.500 L}[/tex]
Molality = 8.595615368 =8.59M
Hence, 8.59 is the concentration of ethyl alcohol when 0.198 kg of ethyl alcohol.
