Question

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?

Answer 1

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

Step-by-step 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
