For the percent absorbance in this lab, two separate experiments were executed. In the first test, we failed to thoroughly mix the water and the grape juice, hence yielding a haphazard linear graph. The second, however, was mixed, and it thus yielded a almost-perfect slope.

 
grape juice/water %transmittance (#1) %transmittance (#2)
10:0 29 29
9:1 34 32
8:2 32 35
7:3 38 43
6:4 49 48
5:5 47 54
4:6 67 62
3:7 70 72
2:8 78 80
1:9 87 91
0:10 100 100

The transmittance rate in this graph showed two minor varying slopes. Again, the second experiment yielded a more precise slope, as the ingredients were thoroughly mixed.
