Answer:
Neutron has no charge while electron has a negative charge and proton has a positive charge
We are given that:
100 mL total solution with 1:50 povidone iodine solution
This means that there is 1 mL of povidone iodine solution
per 50 mL of total solution. Since we are given a total of 100 mL solution,
therefore we have an initial amount of:
pure povidone iodine solution = 2 mL
This amount of pure povidone iodine solution is added or
diluted (most perhaps with water) to make a total of 1000 mL total solution,
therefore the new ratio is:
2:1000 povidone iodine solution
By dividing both sides by 2, this simplifies to
1:500 povidone iodine solution
Answer:
1:500

Answer: Molarity of the solution is 0.813 M.
Explanation:
Given : Mass of NaOH = 97.68 g
Volume of solution = 3 L
The molar mass of NaOH is 39.99 g/mol. Hence, moles of NaOH are calculated as follows.
Molarity is the number of moles of solute present in a liter of solution. Therefore, molarity of given solution is calculated as follows.
Thus, we can conclude that molarity of the solution is 0.813 M.
