1.5 M NaOH is needed to provide 0.75 mol

 

 

What volume of 1.5 M NaOH is needed to provide 0.75 mol of NaOH?

(a) 500L

(b) 5.0 L

(c) 500 mL

(d) 0.75 L

 

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

 

몰농도 = 용질 mol/ 용액 L

( 설명 https://ywpop.tistory.com/3222 )

 

용액 L= 용질 mol/ 몰농도

= 0.75 mol / (1.5 mol/L) = 0.5 L

 

 

: (c) 500 mL
