Text Solution

AI Generated Solution

To calculate the amount of hydrogen peroxide (H₂O₂) present in 10 mL of a 25 volume H₂O₂ solution, we can follow these steps: ### Step 1: Understand the concept of "volume" in H₂O₂ solutions The term "25 volume" means that 1 volume of H₂O₂ solution can produce 25 volumes of oxygen gas (O₂) when decomposed. This implies that 1 liter of this solution will produce 25 liters of O₂. ### Step 2: Calculate the amount of oxygen produced by the solution At Normal Temperature and Pressure (NTP), 1 mole of gas occupies 22.4 liters. Therefore, to find out how many grams of H₂O₂ are needed to produce 25 liters of O₂, we can set up the following relationship: ...
