If you change the subscripts it would change the reactants or products and then you would be solving a different formula, you would change what the chemical is
The density of a pure gold is 19.32g/cm3
if the volume is 4.30 cm3 then we can calculate the mass using the formula mass=density x volume
mass=19.32*4.30
mass=83.076g
As temperature increases, the average kinetic energy of a sample of gas molecules decreases.
