(4x^2-9)(2x+1)=0
(2x-3)(2x+3)(2x+1)=0
<u><em>Answer:</em></u>
Section 1: 5.59%
Section 2: -2.16%
Section 3: -10.82%
Section 4: -6.54%
Section 5: -2.16%
Section 6: 7.86%
<u><em>Explanation:</em></u>
<u>The formula to calculate the percent change in mass is given as:</u>

<u>1- Section 1:</u>
Old mass = 7.83 g and New mass = 8.268 g
5.59%
<u>2- Section 2:</u>
Old mass = 7.4 g and New mass = 7.24 g
-2.16%
<u>3- Section 3:</u>
Old mass = 7.3 g and New mass = 6.51 g
-10.82%
<u>4- Section 4:</u>
Old mass = 7.49 g and New mass = 7.0 g
-6.54%
<u>5- Section 5:</u>
Old mass = 7.4 g and New mass = 7.24 g
-2.16%
<u>6- Section 6:</u>
Old mass = 7.89 g and New mass = 8.51 g
7.86%
Hope this helps :)
