mass (in g) of chlorine in 25.25 L of tetrachloroethene

 

 

Tetrachloroethene (C2Cl4) is commonly used as a dry cleaning solvent

with a density of 1.62 g/cm3.

Determine the mass (in g) of chlorine in 25.25 L of tetrachloroethene.

 

---------------------------------------------------

 

25.25 L = 25250 mL C2Cl4

 

 

 

25250 mL × (1.62 g/mL) = 40905 g C2Cl4

 

 

 

> C2Cl4의 몰질량 = 165.83 g/mol

> Cl의 몰질량 = 35.45 g/mol

 

 

 

40905 g C2Cl4 × (4×35.45 g Cl / 165.83 g C2Cl4)

= 40905 × (4×35.45 / 165.83)

= 34978 g Cl

 

 

 

답: 3.498×10^4 g
