Answer:

47.2%

Explanation:

Judging from the question given, the theoretical yield is 10g because the student had already made his/her calculation and was expecting to get the same result at the end of the experiment. But he could only get 4.72g from the experiment.

Now, The percentage yield can be obtain as follows

Experimental yield = 4.72g.

Theoretical yield = 10g

%yield = Experimental yield /Theoretical yield x100

% yield = 4.72/10 x100

%yield = 47.2%

Therefore, the percentage yield of the experiment is 47.2%

How many moles of aluminum do 4.40×1024 aluminum atoms represent?
zhannawk [14.2K]
For this problem we use the Avogadro's number which is an empirical value that relates the number of particles to the number of moles. Its approximated value is 6.022×10²³ atoms/mole. The solution is as follows:

4.40×10²⁴ aluminum atoms * 1 moles/6.022×10²³ atoms = 7.306

Thus, there are 7.306 moles of aluminum.
