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
<h3>14.8% of H2O2</h3>

Answer
There are several different educational paths that will lead you to a degree in nursing depending on your background and preference. You will need to go to school for a minimum of two years for an associates degree in nursing (unless you already have a degree in another major) and a maximum of four years to obtain a BSN degree. There are some diploma programs still in operation (no degree), but it is increasingly important to have a degree in nursing to be competitive.
