Question

What is the osmotic pressure of the solution obtained by mixing 300 cm3?

Answer 1

Answer:

426.335someting cane

Explanation:

Osmotic pressure of solution

100 ml of 1.5% urea

and 100ml 3.42% of cane sugar

Molar concentration in 200ml,we have

solutes = 1.5/60 moles urea + 3.42/342 moles cane sugar

= 0.025 + 0.01

= 0.035 moles

=> 0.035 X 1000

-----------------------

200

=> 0.175 M

Since cane sugar and urea are non ionic we will not multiply by the any factor

therefore,

pi = cRT

= 0.175 X 8.314 X 293

= 426.335 Pa
