Answer:
150
Explanation:
- C₄H₂OH + 6O2 → 4CO2 + 5H₂O
We can <u>find the equivalent number of O₂ molecules for 100 molecules of CO₂</u> using a <em>conversion factor containing the stoichiometric coefficients of the balanced reaction</em>, as follows:
- 100 molecules CO₂ *
= 150 molecules O₂
150 molecules of O₂ would produce 100 molecules of CO₂.
Answer:
a. Approximately .
b. Approximately .
Explanation:
The unit of concentration "" is equivalent to "
", which means "moles per liter."
However, the volume of both solutions were given in mililiters . Convert these volumes to liters:
.
.
In a solution of volume where the concentration of a solute is
, there would be
(moles of) formula units of this solute.
Calculate the number of moles of formula units in each of the two solutions:
Solution in a.:
.
Solution in b.:
.
What volume of that (same as
)
solution would contain that many
For the solution in a.:
.
Convert the unit of that volume to milliliters:
.
Similarly, for the solution in b.:
.
Convert the unit of that volume to milliliters:
.
