Canvas Classes · Accepted Answer

Strategy:
 "Volume strength" of  is defined as the volume of Oxygen gas (in mL or L) produced at STP by the decomposition of 1 unit volume (1 mL or 1 L) of the  solution.

Step 1: Analyze decomposition stoichiometry
Reaction: .
 moles of  () produce  () of  at STP.

Step 2: Calculate Oxygen from the specific sample
Given:   is in  solution.
Since  gives , then  gives .
 provides  of  gas.

Step 3: Determine Volume Strength
Volume strength .
