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?

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

i think is conclusions.i think so
