Squeezing just the juices out of the orange, like with your hand or whatever you use, is a physical change. yes :)
<span>Answer is: Van't Hoff factor
(i) for this solution is 1.051 .
Change in boiling point from pure solvent to solution: ΔT
=i · Kb · b.
Kb - </span><span>molal boiling point elevation constant</span><span> is 0.512°C/m.
b - molality, moles of solute per kilogram of solvent.
b = 1.26 m.
ΔT = 101.63°C - 100</span>°C = 1.63°C.
i = 1.63°C ÷ (0.512°C/m · 1.26 m).
i = 1.051.
Answer:
Approximately 5.646 * 10^-17 moles
Explanation:
Avagardo's number is approximately 6.022 * 10^23 molecules. Therefore, dividing 3.4 * 10^7 by avagadro's number yields approximately 5.646 * 10^-17 moles. Hope this helps
Answer:
About 7.9 L.
Explanation:
We can utilize the ideal gas law. Recall that:
Because the amount of carbon dioxide does not change, we can rearrange to formula to:
Because the right-hand side stays constant, we have that:
Hence substitute initial values and known final values:
Therefore, the final volume is about 7.9 L.
