Answer:
a) Mass = 3.9 g
b) Mass = 0.395 g
Explanation:
Density is related to the mass and volume of a substance by the relation:

a) Given:
Volume = 4.00cm3
Density = 0.97 g/cm3
Based on equation (1)

b) Given:
Volume = 125 ml
Density = 3.16 g/L
1 ml = 0.001 L
Therefore, 125 ml = 0.125 L
Based on equation (1)

Answer:
Extensive properties, such as mass and volume, depend on the amount of matter being measured. Intensive properties, such as density and color, do not depend on the amount of the substance present.
Answer:
The heat and light released by fire comes from the breaking of chemical bonds. ... The mass of each molecule, before burning, exceeds the total mass of its atoms by a tiny amount that is equivalent (through E=mc²) to the total energy of all its atomic bonds.
