Determine the molarity of a iron (II) nitrate aqueous solution that is 24% by mass. The density of the solution is 1.03 g/cm3
a. 0.00137 M
b. 1.37 M
c. 4.10 M
d. 4.35 M
e. 1.30 M

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

the dependant variable is spilled water

the independent is the heat
