First, you convert liters to moles. 
Usually you have to go to grams but this is STP.
Get moles directly by dividing the 4 by STP (22.4)

About 

 or 0.18 moles whichever your teacher prefers
 
        
        
        
Answer:
HCN < HOCl < HF  
Explanation:
The larger the Kₐ value, the stronger the acid.
6.2 × 10⁻¹⁰ < 4.0 × 10⁻⁸ < 6.3 × 10⁻⁴
    HCN      <     HOCl    <      HF
  weakest       stronger    strongest
 
        
             
        
        
        
We know that each millimeter contains 10⁻³ meters. Writing this as a ratio:
1 mm : 10⁻³ m
We require a conversion from m³ to mm³, so we must take the cube of the ratio we have made:
1 mm³ = (10⁻³)³ m³
Therefore, the conversion used will be:
(1 mm / 10⁻³ m)³
When we multiply by this conversion, we will get:
32 m³ = 32 x 10⁹ mm³
