Question

calculate the mole fraction of each compound in 233g of CO2 in 0.409L of water (density of water is 1.00g/mL).​

Answer 1

Answer:

mole fraction of Co2 is 0.99

mole fraction of H2o is 0.003

Explanation:

mole fraction formula XA= nA/nA+nB

XB= nB/nB+nB

XA+XB= 1

where n= moles

moles= weight/ moler mass

mole of CO2 = 233/44.01= 5.29 moles

mole of H2O = 0.40/18.0153= 0.02 moles

therefore according to equation mole fraction of co2 =5.29/0.02+5.29=0.99

mole fraction of h2o = 0.02/0.02+5.29=0.003
