Moles of ethylenediamine contained in 10.4 ml of 25% ethylenediamine solutions is 0.0388 moles
A mole is defined as 6.02214076 × 10²³ of some chemical unit, be it atoms, molecules, ions, or others.
Given:
volume=9.8 mL
Density= 0.960 g/mL
Percent concentration of solution= 25%
mass of nickel chloride=1.85 g
mass = density * volume
mass = 0.950 g/ml * 9.8 ml
mass = 9.31g
Since it is a 25 % solution of Ethylenediamine
mass of ethylenediamine in 25 moles
moles of ethylenediamine = [tex]\frac{2.33g}{60g/mol}[/tex] =0.0388 moles
Thus, Moles of ethylenediamine contained in 10.4 ml of 25% ethylenediamine solutions is 0.0388 moles.
