Question

I don't really get this the one on the bottom but you use the top to solve

Answer 1

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%

How to get the percentages?

Here we just need to use the given formula:

$percent\ disolved = \frac{initial\ mass - \ final \ mass}{initial \ mass}*100 \%$

For the 0% acid, the initial and final mass are the same:

initial mass = final mass = 10.3g

Then the percent dissolved is:

$percent\ disolved = \frac{10.3g - 10.3g}{10.3g}*100 \% = 0 \%$

For the 33% acid we have:

• initial mass = 10.1g
• final mass =  10g

Then:

$percent\ disolved = \frac{10.1g - 10g}{10.1g}*100 \% = 1 \%$

For the 66% acid:

• initial mass = 10g
• final mass =  9.8g

$percent\ disolved = \frac{10g - 9.8g}{10g}*100 \% = 2 \%$

for the 100% acid:

• initial mass = 9.9g
• final mass =  9.5g

$percent\ disolved = \frac{9.9g - 9.5g}{9.9g}*100 \% = 4.2 \%$
