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:

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

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

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

Please solve and i’ll give u brainliest

Usimov [2.4K]

Solution:

Given angles: w + 8° and 48°
w + 8 + 48 = 180

<u>Solve for w in the equation "w + 8 + 48 = 180".</u>

=> w + 8 + 48 = 180
=> 56 + w = 180
=> w = 180 - 56
=> w = 124°

The value of w is 124.

$$ PS = \frac{4}{3} x$

Solution:

Given PRQ is a triangle.

ST is a line parallel to RQ.

$$PT = x, \ PQ = 3x, \ SR=\frac{8}{3}x$

$TQ=PQ-PT$

$TQ=3x -x=2x$

<u>Triangle proportionality theorem,</u>

<em>If a line parallel to one side of a triangle intersects the other two sides, then it divides the two sides proportionally.</em>

$$\frac{PS}{SR} =\frac{PT}{TQ}$

$$\frac{PS}{\frac{8}{3} x} =\frac{x}{2x}$

Do cross multiplication, we get

$$ PS \times 2x=x \times \frac{8}{3} x$

Divide by 2x on both sides, we get

$$ PS = \frac{4}{3} x$
