Answer:
Density is a measure of the amount of mass that is packed into a specific volume.
Explanation:
Density=mass/volume
C. Temperature. The greater the temperature of a substance the greater the average kinetic energy of the particles that made up the substance.
Answer:
C₆H₈O₆
Explanation:
The molecular formula of given compound is C₆H₈O₆. Because there are six carbon, six oxygen and eight hydrogen atom present in this compound.
The molecular weight of following compound is,
C₆H₈O₆
C = 12 amu
H = 1 amu
O = 16 amu
C₆H₈O₆ = 12×6 + 1×8 + 16×6
C₆H₈O₆ = 72 +8 + 96
C₆H₈O₆ = 176 g/mol
Answer:
Explanation:
Heat of combustion of 
= -1366.8 kJ/mol
Heat of formation of
