For aqueous 30% w/w H₂O₂ of specific gravity 1.5, select correct statements.
Options:(select one or more)
Answer:
C
Solution:
One litre weighs 1500 g and contains 450 g H₂O₂. Thus %w/v=45% and concentration=450/34=13.24 M, disproving A,B. In 100 g, mole fraction=(30/34)/[(30/34)+(70/18)]=0.185≈0.18, C. D uses the wrong concentration 200/34. Only C. The delayed printed line labels Q7 and belongs to this item, not Q9.
