Answer:
14.8% of H2O2
Explanation:
Based on the redox reaction of H2O2/MnO4- is:
2MnO4- + 5H2O2 + 6H+ ⇄ 2Mn2+ + 5O2 + 8H2O
<em>2 moles of KMnO4 react with 5 moles of H2O2</em>
<em />
To solve this question we need to find the moles of KMnO4 until reach the endpoint. Using the balanced reaction, we can find the moles of H2O2 that must be converted to grams using its molar mass -Molar mass H2O2: 34.015g/mol-:
<em>Moles KMnO4:</em>
0.0297L * (1.4686eq/L) = 0.04362eq MnO4- * (1mol / 5eq) = 0.008723 moles MnO4-
<em>Moles H2O2:</em>
0.008723 moles MnO4- * (5mol H2O2 / 2mol MnO4-) = 0.02181 moles H2O2
<em>Mass H2O2:</em>
0.02181 moles H2O2 * (34.015g/mol) = 0.7418g H2O2
<em>%:</em>
0.7418g H2O2 / 5.0mL * 100

Medical asepsis isn't known for that instead it's Surgical asepsis that is known for also being called sterile technique.
The nursing action that reduces the risk of falling as a patient is getting into or out of a bathtub is to place a skidproof disposable bath mat in front of the tube.
<h3>What is a skidproof disposable bath mat?</h3>
A skidproof disposable bath mat is a functional material that is made up of quick-dry microfiber surface which helps to provide friction for wet surfaces of the bathroom.
It is the duty of the nurse to educate the patient on various measures to take in order to prevent any impending harm.
Therefore, to prevent or reduce the risk of falling in the bathtub, the nurse should place a skidproof disposable bath mat in front of the tube.
