Question
empirical formula for N3O6 Use the molarity equation to solve the following questions. what is the molarity of a solution with 1.5 moles NaOH is 600 mL of solution? b. How many moles of HCl are needed to make 1.5L of a 2 M solution? Complete the mass-mass stoichiometry problem. (Step one has been done for you) Tryptophan, a nutrient naturally found in our diet, is used by the body to synthesize many necessary bodily chemicals. In one of the processes, tryptophan is changed to hydrotryptophan, (5HTP) which is further changed to serotonin. C_11H_12N_2O_3(5HTP) rightarrow C_10H_12N_2O + CO_2_(serotonin) If 10 trams of 5HTP are used, bow many grams of serotonin would be synthesized?Explanation / Answer
molarity = number of moles * 1000/volume of solution
M = 1.5 *1000/600
M = 2.5
for HCl,
2 = n/1.5
n = 3 moles
number of moles of SHTP = 10/220 = 0.0455
1 mole of SHTP produces 1 mole of serotonin
number of moles of Serotonin = 0.0455
mass of serotonin = 0.0455 * 176 = 8.008 g
