1Transfer the necessary data from Data Table 1 of Exercise 1 into Data Table 2.

2. Calculate the percent of total mixture for each substance by dividing the mass of the substance by the mass of the mixture of solids and multiplying by 100. See equation below.

% of total mixture=

Mass of substance (g)/ mass of mixture of solids

100
