In the space below, combine two of the above equations algebraically to obtain the thirdequation. Indicate the number of each reaction on the shorter lines.2.Show the calculation of the final mass of solution in each of the three experiments thatyou will perform in this lab exercise. (Assume the density of each solution is 1.00 g/mL.)3.Show the calculation of the number of moles of each reactant in each of the experimentsin this assignment. (How do you get moles from grams
