Answer:
0.24mole
Explanation:
Given parameters:
Number of molecules = 14.35 x 10²² molecules;
Unknown = number of moles of H₃PO₄
A mole of a substance is the quantity of matter that contains the avogadro's number of particles.
This number is given as 6.02 x 10²³ particles. The particles can be atoms, molecules, protons, electrons e.t.c
6.02 x 10²³ molecules is contained in 1 mole of any substance
14.35 x 10²² molecules will contain: = 0.24mole
Answer:
A.
B.
Explanation:
Hello!
In this case, since the undergoing chemical reaction between nitrogen and hydrogen is:
Thus we proceed as follows:
A. Here, we first need to compute the moles of ammonia yielded by each reactant, in order to identify the limiting one:
Thus, since nitrogen yields the fewest moles of ammonia, we realize it is the limiting reactant, so the theoretical yield, in grams, of ammonia is:
B. Finally, since the actual yield of ammonia is 1.23, the percent yield turns out:
