Density of an object is computed by dividing its mass by its volume. D = M / V
Solution:
D = 500 g / 2.75 cm3
D = 181.82 g/cm3
Further, density of an object is computed by dividing its mass by its volume. D = M / V
However, since Volume is the missing component in the equation. Mass of an object is divided by its density to get its volume. V = M / D
<span>Volume of Gold nugget = 50 g </span>/<span> 19.3g/cm3 = </span>2.59cm3
<span>Volume of Iron Pyrite nugget = 50 g </span>/ <span>5.0g/cm3 = </span>10cm3
Polymerization is the chemical reaction between monomer molecules. The result of the reaction are polymer chains or three-dimensional networks. A polymer is build from several blocks - monomers. Polymerization is most directly responsible in determining the primary structure of a protein.
The substance has the specific heat capacity of steel and is therefore probably steel.
Let the specific heat of the unknown lump of substance be 
.
Energy Exchange = Specific Heat ⨯ Mass ⨯ Temperature Change
Energy the Hot Lump Lost = Energy the Cold Water Gained
Water has a specific heat of 
and a density of 
. 25.0 milliliters of water thus has a mass of 25.0 grams.
Steel has a specific heat of approximately 
. This substance is thus <em>probably </em>steel.
