A mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. ... A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral matter.
Density of gasoline is 0.737 g/mL and volume of tank is 13.0 gal.
Since, 1 US gal=3.78 L
Volume of tank in L will be:
Also, 1 L=1000 mL
Thus,
Mass of gasoline can be calculated as follows:
m=d×V
Here, d is density and V is volume thus,
Therefore, mass of gasoline will be 
.
mass * temp change * specific heat
make sure the specific heat value is in Joules
The law of conservation of mass states that mass can neither be created nor destroyed. For example in an isolated system, mass of the reactants is equal to the mass of the products. Thus, mass or the quantity of the system under consideration will remain unchanged through any physical or chemical process.
In the given example, the board initially has a mass of 750 g. It is physical transformed to sawdust by grinding. Based on the conservation of mass, the pile of sawdust would still weigh 750 g.
