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

Answer: no cheating on the state test
Step-by-step explanation:
Answer:
x = 8
Step-by-step explanation:
Step 1: Write equation
2(x + 5) = 26
Step 2: Solve for <em>x</em>
<u>Distribute 2:</u> 2x + 10 = 26
<u>Subtract 10 on both sides:</u> 2x = 16
<u>Divide both sides by 2:</u> x = 8
Answer:
im quite confused with the way its been layed out
cant tell if ur multiplying of its a X
Step-by-step explanation:
(2^8 times 5 ^-8 times 1) ^-2x times 5^-2 over 2^3 times 4 times 2 ^28
(2^-16x times 5^10x times 5^-2 over 8 times 4 times 2^28
2^16=28 times 5 ^10x
