Answer: There are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
Explanation:
Given: = 2.25 L,
= 9.0 mol
= 1.85 L,
= ?
Formula used to calculate the moles of helium are as follows.
Substitute the values into above formula as follows.
Thus, we can conclude that there are 7.4 moles of helium gas present in a 1.85 liter container at the same temperature and pressure.
Answer:
<u><em>Pentane </em></u>
Explanation:
since we have in here CH3-CH2-CH2-CH2-CH3 5 Carbon atoms and 12 Hydrogen making it
Answer:
Concentration of the original solution: approximately
.
Explanation:
Notice that the concentration of the solution is in the unit
. However, the unit of the two volumes is
. Convert the unit of the two volumes to
to match the unit of concentration.
.
.
Calculate the number of moles of molecules in that
of
solution:
.
is a monoprotic acid. In other words, each
would release up to one proton
.
On the other hand, is a monoprotic base. Each
formula unit would react with up to one
.
Hence, molecules and
formula units would react at a one-to-one ratio.
.
Therefore, that of
molecules would neutralize exactly the same number of
formula units. That is:
.
Calculate the concentration of a solution where
