5. Mr. Hinze wants to know how much mass his car is but can't afford a scale that big so he decided to test it with Newton's Second Law. He accelerated his car at 10 m/s2 and
found out that when it moved it had 15,000 Newtons of force.
How much mass is Mr. Hinze's car in Kg?

Because of the reaction stoichiometry (detailed information given below).

Explanation:

Well, reaction stoichiometry determines relationships between reactants and products in a chemical reaction. For example, if the relationship between reactants and/or products is 1 to 1 (e.g. CO + H2O => CO2 + H2), the product is produced as much as the limiting reactant(s) (which is less than the other one in amount) consumed. For example, if 3 moles CO mixed with 0.5 moles of O2 (so O2 is limiting reactant in this case), 0.5 CO2 and 0.5 H2 are produced and 2.5 moles of CO and 0 moles of O2 (because all of O2 consumed) are left over. So, it can be concluded that the reaction stoichiometry has a direct relationship with the amount of the product and the amount of each reactant left over.
