Answer:
Up to
.
Explanation:
The equation for this reaction: is indeed balanced.
Notice that the coefficient of is
while that of
is
.
Therefore, each unit of this reaction would consume units of
while producing
units of
. In other words, this reaction would produce three times as much
as it consumes
.
If all that of
molecules are actually consumed through this reaction, three times as many
molecules would be produced. That corresponds to
of
molecules.
Explanation:
Because molarity is classified as moles of solute per liter of water, dilution of the water may result in a reduction of its concentration.
Therefore, because the amount of moles of solute has to be constant for dilution, you will use the molarity and volume of that same target solution to calculate how many moles of solute will be present in the sample of the stock solution that you dilute.
c =
⇒ n = c ⋅ V
= 0.250 M ⋅ 6.00 L =
1.5 moles HCl
Now all you have to do is figure out what volume of 6.0 M stock solution will contain 1.5 moles of hydrochloric acid
c =
V =
=
=
0.25 L
Expressed in milliliters, the answer will be
→ rounded to two sig figs
