Phenols in 5% solutions are commonly used as disinfectants and antiseptics due to their ability to kill bacteria and viruses. They are often used in healthcare settings, laboratories, and industrial applications to help prevent the spread of infections.
A 5 percent raise on $12.30 would be $0.62.
To calculate the percent of a 5 N H2SO4 solution, you need to know the molarity (moles of solute per liter of solution) and the molecular weight of the solute. Once you have that information, you can use the formula: % = (molarity x equivalent weight) / 10. If you provide the molecular weight of H2SO4, I can help you calculate the percent.
The two constants in this experiment would be the time each cloth square was soaked in the bleach solution (5 minutes) and the size of the cloth squares (assuming they are the same size).
5M NaHCO3 is more concentrated than 5 percent NaHCO3. Molarity (M) measures the concentration of a solution based on the number of moles of solute per liter of solution, whereas percent concentration is based on the mass of the solute per 100 parts of the total solution.
Using 100% acetic acid would be too corrosive and dangerous for household use. Diluting it to 5% in vinegar makes it safer for cleaning and cooking purposes while still maintaining its effectiveness.
