Answer:
Thus, to calculate the stoichiometry by mass, the number of molecules required for each reactant is expressed in moles and multiplied by the molar mass of each to give the mass of each reactant per mole of reaction. The mass ratios can be calculated by dividing each by the total in the whole reaction.
Explanation: Stoichiometry is the field of chemistry that is concerned with the relative quantities of reactants and products in chemical reactions. For any balanced chemical reaction, whole numbers (coefficients) are used to show the quantities (generally in moles ) of both the reactants and products.
The correct answer are:
#1. The measure of gravity on earth determines our weight
#2. The closer an object is to the center of earth, the greater the gravitational force on that object.
#3. Objects in a free fall are constantly picking up speed as they fall back to earth is true.
