Calculate the osmotic pressure (in torr) of 6.00 L of an aqueous 0.958 M solution at 30.°C, if the solute concerned is totally i

cluponka [151]

<u>Answer:</u> The osmotic pressure is 54307.94 Torr.

<u>Explanation:</u>

To calculate the concentration of solute, we use the equation for osmotic pressure, which is:

$\pi=iCRT$

where,

$\pi$ = osmotic pressure of the solution = ?

i = Van't hoff factor = 3

C = concentration of solute = 0.958 M

R = Gas constant = $62.364\text{ L Torr }mol^{-1}K^{-1}$

T = temperature of the solution = $30^oC=[30+273]K=303K$

Putting values in above equation, we get:

$\pi=3\times 0.958mol/L\times 62.364\text{ L. Torr }mol^{-1}K^{-1}\times 303K\\\\\pi=54307.94Torr$

Hence, the osmotic pressure is 54307.94 Torr.

The larvae of mosquitoes live in water and provide food for fish and other wildlife, including larger larvae of other species such as dragonflies. The mosquito larvae themselves consume a lot of organic matter in wetlands, helping recycle nutrients back into the ecosystem.Ramabai Bhimrao Ambedkar was the first wife of B. R. Ambedkar, who said her support was instrumental in helping him pursue his higher education and his true potential. She has been the subject of a number of biographical movies and books. A number of landmarks across India have been named after her.Hydrochloric acid: HCl. Nitric acid: HNO. Phosphoric acid: H3PO. Sulfuric acid: H2SO.

Examine the general structure of a molecule.

Lilit [14]

Answer:

Explanation:

functional groups are specific substituents or atoms within molecules that brings about chemical reactions of those molecules. There is the same or similar chemical reaction in compounds with the same functional groups.

1.)The functional group in Alkyl halides is halogen atom whille

The functional group in Alcohols have

is OH group. There is a double bond in HX or an HOH molecules.

2.)The functional group of carboxylic acid is an organic compound is carboxyl functional group.While The functional group in amine contains a basic nitrogen atom with a lone pair of electrons.

3.)The functional group in ester is a carboxylic acid derivative that is analogous to the Amides

4.) A carboxylic acid has carboxyl functional group. However the hydrogen of the hydroxyl group is can be ionized. In an ester, there is a replacement of hydrogen of acarboxylic acid group by an alkyl group

Can someone provide me with 5 different sentences describing what the boundry type Divergent - Mid-Ocean Ridge is? 10 POINTS!!

Lorico [155]

Answer:

The massive mid-ocean ridge system is a continuous range of underwater volcanoes that wraps around the globe like seams on a baseball, stretching nearly 65,000 kilometers (40,390 miles).

The majority of the system is underwater, with an average water depth to the top of the ridge of 2,500 meters (8,200 feet).

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart.

As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes.

tell me if this is wrong please
