Volume of alcohol = 4 mL of alcohol
Volume of water required = 194 mL
<h3>What is a dilution factor?</h3>
A dilution factor is a ratio of the solute to solvent. It is used to express how much of the original stock solution is present in the total solution.
Given the following dilution to make:
obtain 200 ml of an isopropyl solution using the dilution ratio 1 : 20 of alcohol to water.
Total volume = 200 ml
Volume ratio of alcohol to solution will be 1/50 * 200
Volume of alcohol = 4 mL of alcohol
Then volume of water required = 200 m - 4 ml
volume of water required = 194 mL
In conclusion, the dilution is done using the dilution factor.

Answer:
A good thermal conductor
Explanation:
A conductor creates and transfers heat for example: a metal pot. While and insulator just keeps whatever is already hot at the same temperature.
Prokaryotes dont have a nucleus
Answer:
the answer will be enzyme
During the prophase the nucleoli in the nucleus disappear. The chromatin fibers become tightly ccoiled and condense into chromosomes. Chromosomes line up in pairs and are joined at the centromere. In the cytoplasm, the spindle fibers begin to formand are made of microtubules.
