Answer:

The osmotic pressure is 8.85 atm

Explanation:

Step : Data given

Mass of glucose = 55.0 grams

Volume of water =800.0 mL

Temperature = 10.0 °C

Step 2: Calculate moles glucose

Moles glucose = mass glucose / molar mass glucose

Moles glucose = 55.0 grams / 180.156 g/mol

Moles glucose = 0.305 moles

Step 3: Calculate osmotic pressure

π = iMRT

⇒ with π = the osmotic pressure = TO BE DETERMINED

⇒ with i = the van't Hoff factor for glucose = 1

⇒ with M = the concentration = moles / volume = 0.305 moles / 0.800 L =0.381 M

⇒ with R = the gas constant = 0.08206 L*atm*mol¨K

⇒ with T = the temperature = 10.0 °C = 283 K

π = 1* 0.381 *0.08206 * 283

π = 8.85 atm

The osmotic pressure is 8.85 atm

1A: Consider these compounds:

Setler [38]

Solution :

Compound Ksp

$PbF_2$ $3.3 \times 10^{-8}$

$Ni(CN)_2$ $3 \times 10^{-23}$

FeS $8 \times 10^{-19}$

$CaSO_4$ $4.93 \times 10^{-5}$

$Mg(OH)_2$ $5.61 \times 10^{-12}$

Ksp of $$Ni(CN)_2$ and both compounds dissociate the same way. Hence $Mg(OH)_2$ is more soluble than $(B). \ Ni(CN)_2$

$Mg(OH)_2$ is less soluble than $(A). \ \ PbF_2 \ ()Ksp \ PbF_2 > Ksp \ \text{ of } \ Mg(OH)_2$

It is not possible to determine CD - $FeS \text{ or} \ CaSO_4$ is more or less soluble than $Mg(OH)_2$ as though they have a different Ksp values their molecular dissociation is also different and they may have a close solubility values.

$Ni(OH)_2$ can be directly compared with PbS, $AlPO_4, MnS$

$\text{For } \ Ni(OH)_2$

$AB_2(s) \rightarrow A^{2+} + 2B^{-}$

$Ni(OH)_2(s) \rightarrow Ni^{2+} + 2OH^-$

1-s s 2s

Ksp = $[A2+][B-]^2 = s \times (2s)^2 = 4s^3$

Hence they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.

For Silver Chloride

$AB(s) \rightarrow A^{x+}+B^{x-}$

$AgCl(s) \rightarrow Ag^+ + Cl^-$

1 - s s s

Ksp $=[A^{x+}][B^{x-}]=s \times s = s^2$

Hence, they can be directly compared by Ksp values, smaller the Ksp, smaller the solubility.

Which statement is true about heat transfer? *

Mrrafil [7]

Answer: A

Explanation:

heat always passes from a warmer object to a cooler object until all objects are the same temperature. Conduction is how heat travels between objects that are touching. Conduction travels fastest through solids, but liquids and gases can also conduct heat.
