Answer:
i think its A
Step-by-step explanation:
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:
![percent\ disolved = \frac{initial\ mass - \ final \ mass}{initial \ mass}*100 \%](https://tex.z-dn.net/?f=percent%5C%20disolved%20%3D%20%5Cfrac%7Binitial%5C%20mass%20-%20%5C%20final%20%5C%20mass%7D%7Binitial%20%5C%20mass%7D%2A100%20%5C%25)
For the 0% acid, the initial and final mass are the same:
initial mass = final mass = 10.3g
Then the percent dissolved is:
![percent\ disolved = \frac{10.3g - 10.3g}{10.3g}*100 \% = 0 \%](https://tex.z-dn.net/?f=percent%5C%20disolved%20%3D%20%5Cfrac%7B10.3g%20-%2010.3g%7D%7B10.3g%7D%2A100%20%5C%25%20%3D%200%20%5C%25)
For the 33% acid we have:
- initial mass = 10.1g
- final mass = 10g
Then:
![percent\ disolved = \frac{10.1g - 10g}{10.1g}*100 \% = 1 \%](https://tex.z-dn.net/?f=percent%5C%20disolved%20%3D%20%5Cfrac%7B10.1g%20-%2010g%7D%7B10.1g%7D%2A100%20%5C%25%20%3D%201%20%5C%25)
For the 66% acid:
- initial mass = 10g
- final mass = 9.8g
![percent\ disolved = \frac{10g - 9.8g}{10g}*100 \% = 2 \%](https://tex.z-dn.net/?f=percent%5C%20disolved%20%3D%20%5Cfrac%7B10g%20-%209.8g%7D%7B10g%7D%2A100%20%5C%25%20%3D%202%20%5C%25)
for the 100% acid:
- initial mass = 9.9g
- final mass = 9.5g
![percent\ disolved = \frac{9.9g - 9.5g}{9.9g}*100 \% = 4.2 \%](https://tex.z-dn.net/?f=percent%5C%20disolved%20%3D%20%5Cfrac%7B9.9g%20-%209.5g%7D%7B9.9g%7D%2A100%20%5C%25%20%3D%204.2%20%5C%25)
