g/mL of NaCl in a 0.250 M solution

 

 

How many grams per mililiter of NaCl

are contained in a 0.250 M solution?

 

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

 

0.250 M NaCl 용액 = 0.250 mol NaCl / 1 L 용액

( 참고 https://ywpop.tistory.com/3222 )

 

 

 

NaCl의 몰질량 = 58.44 g/mol 이므로,

(0.250 mol / 1 L) (58.44 g / 1 mol) (1 L / 1000 mL)

= (0.250) (58.44) (1 / 1000)

= 0.01461 g/mL

 

 

 

답: 0.0146 g
