From the information given, the total volume of rubbing alcohol is 88.2 ml
68.6 % of this volume is isopropanol.
We will assume 88.2 ml represents 100% volume, so the volume of water will be 31.4 %
The volume of isopropanol is
68.6/100 x 88.2 → 0.686 × 88.2 = 60.505 ml
The volume of isopropanol is 60.5 ml.
Volume of water will be 88.20 - 60.5 = 27.7 ml
(27.7 / 88.2 × 100 = 31.4% )
Adding 60.5 ml of isopropanol to 27.7 ml of water to make up 88.2 ml will give 68.6 % v/v isopropanol to water solution.
Answer:
8 possible microstates.
Explanation:
Supposed we tossed three (3) coins (a nickel, a dime, and a quarter).
The possible outcomes can be seen as follows.
Coin
1st. +1 +1 +1 -1 +1 -1 -1 -1
2nd +1 +1 -1 +1 -1 +1 -1 -1
3rd +1 -1 +1 +1 -1 -1 +1 -1
There 8 (eight) microstates are possible.
The first orbital will have 2 electrons, and the other two will have only 1 electron. So, strat filling each orbital with 1 electron, and when they each get one, then start over, so for 4 electrons, the first one will have 2 electrons in the orbital.
Good the equation is balanced already
3rd option please and good luck hope you pass...........
