Answer:
10%
Explanation:
The percent by volume of acetone is given by the following formula:
% v/v = Volume of acetone / Total Volume * 100%
Now we <u>calculate the total volume of the solution</u>:
Total Volume = Volume of Acetone + Volume of Water
Total Volume = 50 mL + 450 mL = 500 mL
Then we <u>calculate the percent by volume:</u>
% v/v = 50 mL / 500 mL * 100 % = 10%
Answer:
The correct answer to this question is a prokaryotic cell.
Explanation:
Prokaryotes have circular DNA and a cell wall, whereas eukaryotes have their DNA packaged into chromosomes and may not have a cell wall (as is the case in animal cells).
Hope this helps!

6.002*1023 molecules 1mole
<h2><u>Answer:</u></h2>
It wasn't an adjustment in the condition of issue on the grounds that the vitality in the can did not change. Additionally, since this was a physical change, the atoms in the can are as yet similar particles. No synthetic bonds were made or broken. You added enough vitality to make a stage change from strong to fluid.
The main changes recorded which don't include framing or breaking substance bonds would bubble and liquefying. Bubbling and liquefying are physical changes as opposed to synthetic changes, so no new items are shaped.
