Archy [21]

Answer: For price-sensitive customers and for customers with no sodium-related health concerns, sodium chloride is an excellent choice. It's effective, inexpensive, easily obtained and usable in any water softener. On the other hand, potassium chloride would be a better choice for other kinds of customers.

What would be the pressure of a 5.00 mol sample of Cl₂ at 400.0 K in a 2.00 L container found using the van der Waals equation?
marusya05 [52]

Answer:

57.478atm

Explanation:

T = 400k

n = 5mol

v = 2.00

a = 6.49L^{2}

b = 0.0652L/mol

R = 0.08206

Formula

P =  \frac{RT}{(\frac{v}{n} )-b} - \frac{a}{(\frac{v}{n} )^{2} }

P = \frac{0.08206 * 400}{(\frac{2.00}{5.00} )-0.0652} - \frac{6.49}{(\frac{2.00}{5.00} )^{2} }

P = \frac{32.824}{0.3348} - \frac{6.49}{0.16}  

P = 98.041 - 40.563

P = 57.478atm
