The volume of HCl gas required to prepare the solution is 101.54 L
<h3>How to determine the mole of HCl </h3>
- Volume of solution = 1.25 L
- Molarity = 3.20 M
- Mole of HCl =?
Mole = Molarity x Volume
Mole of HCl = 3.2 × 1.25
Mole of HCl = 4 moles
<h3>How to determine the volume of HCl </h3>
- Number of mole (n) = 4 moles
- Temperature (T) = 30 °C = 30 + 273 = 303 K
- Pressure (P) = 745 torr = 745 / 760 = 0.98 atm
- Gas constant (R) = 0.0821 atm.L/Kmol
Using the ideal gas equation, the volume of the HCl gas can be obtained as follow:
PV = nRT
Divide both side by P
V = nRT / P
V = (4 × 0.0821 × 303) / 0.98
V = 101.54 L

Density = mass/volume. 5000/50= 100 grams per cubic centimeter. No substance on Earth has anywhere near that density. Tops is about 20 for osmium and gold.
During osmosis, a statement which correctly describes the movement of water across a selectively permeable membrane is: 3. Either of these descriptions is correct and equivalent.
<h3>What is osmosis?</h3>
Osmosis can be defined as a process which typically involves the movement of a solvent molecule such as water through a selectively or permeable membrane from a region of high concentration to a region of lower concentration.
This ultimately implies that, the process of osmosis can be illustrated by the movement of water into root hair cells because they are used by the plants to absorb water from the soil.
In conclusion, the movement of water of from high water concentration to low water concentration and from low solute concentration to high solute concentration are statements which correctly describes the movement of water across a selectively permeable membrane during osmosis.

Complete Question:
Which of the answer choices correctly describes the movement of water across a selectively permeable membrane during osmosis.
1. The water will move from high water concentration to low water concentration.
2. The water will move from low solute concentration to high solute concentration.
3. Either of these descriptions is correct and equivalent.
In 1931, the Japan invasion of Manchuria persuaded the Chinese Communist Party and the warlords to unite with the Kuomintang.
<h3>What was the effect of Communism?</h3>
In the year 1931, Japan invaded Manchuria immediately after the Mukeden incident and then installed Manchuko state.
This invasion by the Japanese army on Manchuria was because they felt that a Chinese lieutenant destroyed the South Manchuria Railway by a detonating dynamite.
The imperial Japanese army responded with a full invasion which caused a truce between the Kuomintang and communist party of china, they cooperated against the Japan.
