NaOH 6.22 g이 들어있는 0.315 M NaOH 용액의 부피

NaOH 6.22 g이 들어있는 0.315 M NaOH 용액의 부피

 

 

What volume (in milliliters) of a 0.315 M NaOH solution contains 6.22 g of NaOH?

 

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

 

NaOH의 몰질량 = 40.00 g/mol

6.22 g / (40.00 g/mol) = 0.156 mol NaOH

( 참고 https://ywpop.tistory.com/7738 )

 

 

 

0.156 mol / (0.315 mol/L) = 0.495 L

( 참고 https://ywpop.tistory.com/7787 )

 

 

 

답: 495 mL

 

 

 

 

[참고]

(6.22 / 40.00) / 0.315 = 0.494 L
