100.0 kg of liquid methanol and 100.0 kg of liquid water are mixed in a stirred tank.

Assuming volume additivity of methanol and water, determine the moles and volumes of the two substances in the mixture.


M(l) W(l)
MW (kg / kmol) 32.04 18.01

rho (kg / L) .791 1.00

1. kmol of methanol?

2. kmol of water?

3. Liters of methanol?

4. L of water?

Respuesta :

Answer:

1. kmol of methanol= 3.12 Kmol

2. kmol of water= 5.55 Kmol

3. Liters of methanol=  126.4  L

4. L of water= 100  L  

Explanation:

1. kmol of methanol?

32.04 kg methanol ______________ 1 kmol of methanol

100 kg of methanol_______________ X=  3.12 kmol ofmethanol

2. kmol of water?

18.01 kg water ______________ 1 kmol of wáter

100 kg of wáter_______________ X=  5.55 kmol of water

3. Liters of methanol?

0.791 kg  methanol _______________________1.00  L of methanol

100kg  methanol  _______________________x= 126.4  L of methanol

4. L of water?

1kg  water _______________________1.00  L of water

100kg  water _______________________x= 100  L of water
