Answer: The volume is: " 1.430 cm³ " .
_____________________________
Explanation: 
________________________
Volume, " V = ? ; (unknown, we need to solve for this).
Density, "D = 19.32 g / cm³ ; 
mass , "m" = 27.63 g ; 
_____________________________________________
The formula for density is: 
____________________________________________
 D = m / V ; Divide each side of the equation by: "(1/m)" ; 
 to isolate " V" on one side of the equation; and to solve for "V" ; 
____________________________________________
1/m)*D = (1/m) * (m / V) ;
_______________________________
 to get: 
_______________________________
 D/m = ; ↔  1 / V ; Take the reciprocal of EACH SIDE; to isolate "V" on each side of the equation: 
_____________________________
 m / D = V/1 ↔ V = m / D ;
_____________________________
 V = m / D ; 
_______________________________
 Now, plug in our given values for mass, "m" ; and Density, D"; to solve for "Volume, V " ;
_____________________________________
 V = m / D = (27.63 g) ÷ (19.32 g / cm³) ; 
 
 = (27.63 g) * (1 cm³ / 19.32 g) ;
 
 = (27.63 ÷ 19.32) cm³ ;
 
 = 1.4301242236024845 cm³ ;
 → Round to "4 significant figures" ; 
  = 1.430 cm³ .
