the mole fraction of NaCl of a 1 m solution of NaCl in water

 

---------------------------------------------------

 

1 m 용액 = 용질 1 mol / 용매 1 kg

( 참고 https://ywpop.tistory.com/2667 )

 

 

 

H2O의 몰질량 = 18 g/mol 이므로,

1000 g / (18 g/mol) = 55.56 mol H2O

( 참고 https://ywpop.tistory.com/7738 )

 

 

 

NaCl의 몰분율 = 1 / (1 + 55.56) = 0.01768

( 참고 https://ywpop.tistory.com/2659 )

 

 

 

답: 0.01768
