Question

What is the mole fraction of water in methanol when 18 grams of H2O is added to 32 grams of methanol, CH3OH

Answer 1

Answer:

1/2=0.5

Explanation:

atomic weight of H2O=18

atomic weight of methanol=32

mole =gram weight/atomic weight

mole of H2O = 18/18=1

mole of CH3OH =32/32=1

mole fraction of H2O = mole of H2O/mole of H2O+mole of CH3OH

mole fraction of H2O=1/1+1=1/2=0.5
