Me asap! this is due soon and i don't have all day.
can someone me find the percentage change in mass of each section, using the formula
% change in mass = change in mass/starting mass × 100%
round to the nearest hundredth!
before-
1. 7.83 g
2. 7.4 g
3. 7.3 g
4. 7.49 g
5. 7.4 g
6. 7.89 g
after
1. 8.268 g
2. 7.24 g
3. 6.51 g
4. 7.0 g
5. 7.24 g
6. 8.51 g

Section 1: 5.59%

Section 2: -2.16%

Section 3: -10.82%

Section 4: -6.54%

Section 5: -2.16%

Section 6: 7.86%

Explanation:

The formula to calculate the percent change in mass is given as:

1- Section 1:

Old mass = 7.83 g and New mass = 8.268 g

5.59%

2- Section 2:

Old mass = 7.4 g and New mass = 7.24 g

-2.16%

3- Section 3:

Old mass = 7.3 g and New mass = 6.51 g

-10.82%

4- Section 4:

Old mass = 7.49 g and New mass = 7.0 g

-6.54%

5- Section 5:

Old mass = 7.4 g and New mass = 7.24 g

-2.16%

6- Section 6:

Old mass = 7.89 g and New mass = 8.51 g

7.86%

Hope this helps :)
