Total Weight of Sieve Fractions __________ Percent of Dry weight ___________
Weight of Sand is calculated by subtracting the weight of the beaker from the weight of the beaker and sand.
Cumulative Weight is a running total of the weight of the sand. Write the first weight of sand in the cumulative weight column and add the next weight to this number and write this number in the next space below the first weight. The Total weight of sieve fractions is the bottom number in this column.
Weight percent is calculated by dividing the total weight of the sieve fraction into each sand weight numbers and multiply by 100 so the number is percent. Thus you will have what percent of the total is each sieve fraction.
The cumulative percent is acquired by dividing the total weight of sieve fractions by the appropriate number in the Cumulative weight column. (Do not obtain cumulative percent by adding up weight percentages, as rounding off error may distort the cumulative percentages.
