Answer:
There are two aluminum ions and three sulfate ions; or two aluminum, three sulfur, and twelve oxygen atoms.
Explanation:
Answer:
25.0%
A solution of benzene (C6H6) and toluene (C7H8) is 25.0% benzene by mass. At 25 °C the vapor pressures of pure benzene and pure toluene are 94.2 torr and 28.4 torr, respectively.
120 grams of NaOH means 3 Moles of NaOH because 40 grams (Molecular Weight in grams) is one mole of NaOH.
Each mole of any substance contain Avogadro’s number of molecules ie., 6.022 x (10 to the power 23).
Hence 3 Moles of NaOH contain 3 times of Avogadro’s number of molecules ie., 3 x 6.022 x (10 to the power 23)
Answer:
... Sorry I don't know the answer
A mixture of 3.05-atm N₂(g) and 5.29-atm He(g) exerts a total pressure of 8.34 atm.
<h3>What does Dalton's law of partial pressure state?</h3>
Dalton's law states that in a mixture of non-reacting gases, the total pressure exerted is equal to the sum of the partial pressures of the individual gases.
A mixture of N₂(g) and He(g) exerts a total pressure of 8.34 atm, while the partial pressure of N₂ is 3.05 atm.
We will use Dalton's law to calculate the partial pressure of He.
P = pHe + pN₂
pHe = P - pHe = 8.34 atm - 3.05 atm = 5.29 atm
where,
- P is the total pressure.
- pHe is the partial pressure of He.
- pN₂ is the partial pressure of N₂.
A mixture of 3.05-atm N₂(g) and 5.29-atm He(g) exerts a total pressure of 8.34 atm.
