Respuesta :

Answer : The number of moles of [tex]Ba(NO_3)_2[/tex] are 0.50 moles.

Solution : Given,

Volume solution = 0.25 L

Molarity of solution = 2.00 mole/L

Molarity : It is defined as the number of moles of solute present in one liter of solution.

Formula used :

[tex]Molarity=\frac{\text{ Number of moles of solute}}{\text{ Volume of solution}}[/tex]

Now put all the given values in this formula, we get number of moles.

[tex]2.00mole/L=\frac{\text{ number of moles of }Ba(NO_3)_2}{0.25L}[/tex]

By rearranging the term,

Number of moles of [tex]Ba(NO_3)_2[/tex] = 0.50 moles

Therefore, 0.50 moles of [tex]Ba(NO_3)_2[/tex] are there in the solution.
