If the mass of a material is 47 grams and the volume of the material is 11 cm^3, what would the density of the material be?

_____________________________________________________
The density is:  " 4  g / cm³ " .
_____________________________________________________
                    →  or;  round to:  " 4.2728 g / cm³ " .

Explanation:
_____________________________________________________

Density, "D" =
        mass, "m" [in grams, "g"] / Volume, "V" (mL or cm³;  in this case: "cm³ ") ;

or:  " D = m / V " ; 

Note that "Density, "D" ;  is expressed in terms of "mass per UNIT volume" .
_____________________________________________________
   47 g / 11 cm³   =  (47 / 11) g / cm³ ;

                           =  4.2727272727272727...   g / cm³ ;
_____________________________________________________
 →  Density,  "D"  =  " 4  g / cm³ " .
_____________________________________________________
→  or, round to:           " 4.2728 g / cm³ " .

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
