Answer to Question #272642 in General Chemistry for Ari

Question

38. Sulfuric acid is used to make chlorine dioxide 

for bleaching in the pulp and paper industry. A 

technician in a pulp mill needs to make 275 L of a 

solution containing 4.25 mol/L of sulfuric acid. 

 a. Calculate the volume of concentrated sulfuric 

acid (17.8 mol/L) that the technician must 

measure to make the required solution. 

 b. Determine the volume of water needed to make 

the required solution. 

Answer 1

Moles of sulfuric acid $={ 275×4.25}=1168.75moles$

Volume $= \frac{1168.75}{17.8}=65.66litres$
