Determine the amount of Calcium Chloride dissolved in 2.5 litre of wat

1.	Determine the amount of Calcium Chloride dissolved in 2.5 litre of water that it's osmotic pressure is 0.75 atm. temperature is 27°CVann Hoff factor is 2.47
Answer» EXPLANATION: Solution Given that Osmotic pressure π = 0.75 atm Volume V = 2.5 liter van’t Hoff factor i = 2.47 T = 27 + 273 = 300 K Let w is the amount of CaCl2 required Gas constant R = 0.0821 L atm K-1mol-1 Molar mass of CaCl2M = 1 × 40 + 2 × 35.5 = 111g mol-1 Use the formula of osmotic pressure Plug the values in this formula we get W = 3.43 g Answer Required amount of CaCl2 = 3.42 g.

Answer»

EXPLANATION:

Solution

Given that

Osmotic pressure π = 0.75 atm

Volume V = 2.5 liter

van’t Hoff factor i = 2.47

T = 27 + 273 = 300 K

Let w is the amount of CaCl2 required

Gas constant R = 0.0821 L atm K-1mol-1

Molar mass of CaCl2M = 1 × 40 + 2 × 35.5 = 111g mol-1

Use the formula of osmotic pressure

Plug the values in this formula we get

W = 3.43 g

Answer

Required amount of CaCl2 = 3.42 g.
