Answer:
Vapor pressure of water = 23.14torr
Explanation:
When you made a solution, vapor pressure decreases following Raoult's law:
<em>Where P is vapor pressure and X mole fraction</em>
As vapor pressure of water is 23.77torr we must find the mole fraction of water knowing the solution is 1.500m glucose (That is 1.500 moles of glucose per kg of water = 1000g of water).
1000g of H₂O are, in moles (Molar mass: 18.02g/mol):
1000g H₂O ₓ (1mole / 18.02g) = 55.5 moles of H₂O.
As we know now the solution contains 55.5 moles of water and 1.5 moles of glucose. Thus, mole fraction of water (Solvent) is:
Replacing in Raoult's law, pressure of water above the solution is:
<h3>Vapor pressure of water = 23.14torr</h3>
36 divided by 12 is 3. you need three times as much of the recipe to make 36 brownies. The answer is B
More information is needed to answer this question. Ketones are organic molecules that have the molecular structure RC(=O)R'. R and R' can be any kind of carbon containing structure. An aldehyde is another organic compound that has a functional group having the structure -COH. Both compounds are simple organic compounds. Ketones are widely used for industrial purposes.
Answer:
Ethanol is soluble in water because it has a hydroxyl group which allows it to form hydrogen bonds with the water molecules. This is why hexanol is not soluble in water.
Answer:
0.113 M
Explanation:
Since B and D are on opposite sides of the reaction, the concentration of D increases when the concentration of B decreases. The amount by which D increases is determined by the coefficients of B and D in the balanced chemical equation:
[D]=
(0.045 M)=0.113 M.
