Answer:

0.49 L

Explanation:

T1 = 298.5 K.

V1= 0.54 L

T2= 273.15 K

V2= ?

From Charles law;

V1/T1 = V2/T2

V1T2= V2T1

V2= V1T2/T1

V2= 0.54 × 273.15/298.5

V2= 0.49 L

Calculate the osmotic pressure of a 5.5M glucose solution at 20 degrees Celsius
NeTakaya

The osmotic pressure is a colligative property which depends upon the number of molecules and not the type of molecules

The relation between osmotic pressure and concentration is

πV = nRT

where

π = Osmotic pressure [ unit atm] = ?

V = volume

n = moles

R = gas constant = 0.0821 L atm / mol K

T = temperature = 20°C = 20 + 273.15 K = 293.15 K

also

Molarity = moles / Volume

So

Molarity = n/V = 5.5 M

Putting values

π = MRT

π = 5.5 X 0.0821 X 293.15 = 132.37 atm

Osmotic pressure of given glucose solution will be 132.37 atm

What would be the resulting molarity of a solution made by dissolving 21.9 grams of KCl in enough water to make an 869-millilite
viktelen [127]
Molar mass KCl = <span>74.5513 g/mol

Number of moles:

21.9 / 74.5513 => 0.293 moles

Volume = 869 mL / 1000 => 0.869 L

Molarity = moles / Volume

Molarity = 0.293 / 0.869

=> 0.337 M</span>
