Question

45 gram kcl dissolved in 100 gram of water calculate mole fraction of kcl

Answer 1

Explanation:

Given mass : KCl =45g and H2O =100g

No.of moles of KCl=45÷(39+35.5)=0.604

No.of moles of H2O=100÷(2+16)=5.555

Mole fraction of kcl=0.604÷(0.604+5.555)=0.098

Answer 2

Answer:

:

Given mass : KCl =45g and H2O =100g

No.of moles of KCl=45÷(39+35.5)=0.604

No.of moles of H2O=100÷(2+16)=5.555

Mole fraction of kcl=0.604÷(0.604+5.555)=0.098
