Respuesta :
The volume of space it takes up, whereas its mass is the amount of matter it contains. A sample's density is the quantity of mass per unit of volume.
Equation:
[tex]HClO_4 +NaOH \longrightarrow NaClO_4 + H_2O\\\\[/tex]
HClO₄ is a monoprotic strong acid.
1 mol of HClO₄ reacts with 1 mol of NaOH for neutralization.
Calculating the moles of NaOH [tex]= (0.0789\ M) \times (0.050\ L) = 0.003945\ mol[/tex]
Calculating the needed moles in HClO₄ [tex]= 0.003945 \ mol[/tex]
Calculating the HClO₄ Molarity that is 0.188 M
Calculating the HClO₄ volume that is needed [tex]= \frac{(0.003945\ mol) }{ (0.188\ M)} = 0.020\ L[/tex]
Therefore, the volume of HClO₄ that is needed = 20 mL
