Answer:
ans. is 0.05
Explanation:
molarity=(mole of solute)/(litre of solution)
Answer:
The molarity of the solution is 0.05 [tex]\frac{moles}{L}[/tex]
Explanation:
Molarity (M) is the number of moles of solute that are dissolved in a given volume.
Molarity is determined by the following expression:
[tex]Molarity (M)=\frac{number of moles of solute}{dissolution volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Then you should know the amount of moles of HCL. For that you should know that:
The Avogadro Number or Avogadro Constant is called the number of particles that constitute a substance (usually atoms or molecules) and that can be found in the amount of one mole of that substance. Its value is 6.023 * 10²³ particles per mole. Avogadro's number applies to any substance.
Therefore, applying a rule of three, 6.02*10²² molecules correspond to:
[tex]moles=\frac{6.02*10^{22}*1mole }{6.023*10^{23} }[/tex]
moles=0.1 moles of HCl
Applying the definition of molarity:
[tex]M=\frac{0.1 moles}{2 L}[/tex]
M= 0.05 [tex]\frac{moles}{L}[/tex]
The molarity of the solution is 0.05 [tex]\frac{moles}{L}[/tex]
