Chemistry · Different methods for expressing the concentration of solution: molality, molarity, mole fraction, percentage (by volume and mass both)
used in rocket has the concentration:
\( H_{2} O_{2} \) used in rocket has the concentration:
- A. \( 50 \% \)
- B. 70\%
- C. \( 30 \% \)
- D. 90\%
Step-by-step solution
High-concentration hydrogen peroxide, known as high-test peroxide (HTP), typically 90% or higher, is used as a monopropellant or oxidizer in rockets due to its high decomposition energy. Therefore, the correct concentration is 90%.
