Answer:
2.96 L
Explanation:
We apply the Ideal Gases Law to determine this:
P . V = n . R . T
Firstly we need to know the pressure for the 2.25 moles
P . 1.80L = 2.25 mol . 0.082 L.atm/mol.K . 298K
(We convert T°C to T°K, 25°C + 273 = 298K)
P = (2.25 mol . 0.082 L.atm/mol.K . 298K) / 1.80L
P = 30.5 atm
So now, we apply the pressure value for the new conditions:
30.5 atm . V = 3.7 mol . 0.082 . 298K
V = (3.7 mol . 0.082 . 298K) / 30.5atm = 2.96 L
The best answer to the question presented above would be letter a. Changing the pressure of a system has the highest effect on a gaseous phase. Solids and liquids under pressure make little difference, while gas molecules have many behaviors due to change in pressure.
Answer:
Morality of a solution = 0.38461
Explanation:
Given:
Amount moles in solution = 5 moles of solute
Amount of solvent = 13 kg
Find:
Morality of a solution.
Computation:
⇒ Morality of a solution = Amount of mole solute / Amount of solvent
⇒ Morality of a solution = 5 / 13
⇒ Morality of a solution = 0.38461
⇒ Morality of a solution = 0.385 (Approx)
Chris is correct because the reactants and products do not have to have the same mass, but they do have to weigh the same. Is the correct answer:) Hannah is right because the mass of the reactants was different than the mass of the products. is incorrect
