Answer:
P(H₂) = 807.2 torr
Explanation:
According to the Dalton law, the pressure of mixture of a gas is sum of the partial pressure of its mixing component gases.
P(total) = P1 + P2 + P3 +....
In given problem,
Total pressure is = 794 torr
Partial pressure of water = 13.2 torr
Partial pressure of hydrogen = ?
Solution:
P(total) = P(H₂O) + P(H₂)
P(H₂) = P(total) - P(H₂O)
P(H₂) = 794 torr - 13.2 torr
P(H₂) = 807.2 torr
Answer:
The answer to your question is M
Explanation:
Concentration is represented in a lot of units like Molarity, molality, normality, mass percent, etc.
These units consider the moles or grams of the solute and the volume of the solvent.
Molarity measures the number of moles of solute per liter of solvent and is represented with a letter M (uppercase).
2.50 moles (55.85gramsof Fe/ 1 mole) (6.02 x 10^23 atoms / 1) = 8.41 x 10^25 because there is only one Iron present in the compund.
Answer:
sea water
Explanation:
a sea water can match the following
Given :
Number of moles of CHF₃ is 1.7 .
Solution :
We know, 1 mole of any complex contains 6.022 × 10²³ molecules.
Let, 1.7 moles of CHF₃ contains n numbers of molecules.
So, n = 1.7 × 6.022 × 10²³ molecules
n = 10.2374 × 10²³ molecules
n = 1.0237 × 10²³ molecules
Hence, this is the required solution.
