If I performed an experiment that resulted with a product mass of 15 g (experiemental value). However, based on my stoichiometric calculations (accepted value) I should have gotten a mass of 18 g. What is my percent yield?

The answer is 1.82 j/g°c                  

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
