Answer:
The correct answer is 2.33g of
, A
Explanation:
We can use basic stoich to get this question.
To start, lets convert our grams to moles in order to use our equation. 5.38g of
moles.
We then can use our molar ratio of 13:10. Simply divide by our molar ratio in order to go from moles of
to moles of
. This gets us 0.129335 moles of
.
Now lets convert to grams of
by multiplying by the molar mass of
.
of 
<span>A student conducted an experiment to test the effect of the digestive enzyme pepsin on cooked egg white and potato in the presence of hydrochloric acid at a pH of 1. The most probable inference would be: . Pepsin digests potato because it mainly contains starch. Therefore, the answer would be letter B.</span>
Explanation:
23 are the number of atoms
You have to use Avogadro's number which is 6.02x10^23. The units of Avogadro's number is molecules/mole so you divide the number of molecules by Avogadro's number which will give you the number of moles.
(2.0x10^22 molecules)/(6.02x10^23 molecules/mole)=0.033 moles
