The percentages for each acid are:
- 0% acid ⇒ percentage disolved = 0%
- 33% acid ⇒ percentage disolved = 1%
- 66% acid ⇒ percentage disolved = 2%
- 100% acid ⇒ percentage disolved = 4.2%
<h3>
How to get the percentages?</h3>
Here we just need to use the given formula:
For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:
For the 33% acid we have:
- initial mass = 10.1g
- final mass = 10g
Then:
For the 66% acid:
- initial mass = 10g
- final mass = 9.8g
for the 100% acid:
- initial mass = 9.9g
- final mass = 9.5g

There are 3 even numbers: 2,4,6. If you add 3 there is 4. There is 6 possible outcomes 1,2,3,4,5,6. So the probability is 4/6, 2/3, 66.666....% or 0.6666666....
Answer:
straight line and it needs to go through the origin
