ory 4: Separating of a Blend of Solids

Amounts 1 to 4 below are not written out in your Laboratory Manual. They are really provided here to help you do your calculations more obviously.

1 ) Separating the actual Iron:

Mass of Weighing Dish: _____0. 6_____g

(Read most masses to the decimal places allowed by the balance/scale, commonly one or two decimals, i. elizabeth. a tenth or a hundredth of a gram. )

Mass of Considering Dish additionally Solids Mix: ___5. 1_______ g

Mass of Solids Mixture: _____4. 5_____ g

Mass of Weighing Newspaper: ____0. 9______g

Mass of Weighing Newspaper plus Flat iron: ____2. 1______g

Mass of Iron: ____1. 2______g

2 . Separating out the Sand:

Mass of Evaluating Dish: ___. 6_______g

Mass of Considering Dish in addition Sand: ___1. 7_______g

Mass of Fine sand: _____1. 1_____g

3. Isolating out the Benzoic Acid:

Mass of Conventional paper Cup (to be used in #4 below): ____10. 3______ g

Mass of Filtering Paper: _____1_____g

Mass of Filter Conventional paper plus Benzoic Acid after complete drying out: _____1. 7_____g

Mass of Benzoic Acid solution: _____. 7_____g

4. Isolating out the Sodium:

Mass of Paper Glass plus Salt Chloride

after complete evaporation of water: ____11. 3______g

Mass of Salt Chloride

(use Mass of Paper Cup from #3 to calculate): ____1. 0______g

Mass (g)Percent in Mixture*

Straightener filings1. 2g26. 67%

Sand1. 124. 44%

Table Salt1. 022. 22%

Benzoic Acid solution. 715. 56%

*Follow guidelines of calculations with Significant Figures

Compute the Percent of each Element (iron, sand, salt, benzoic acid) in the Mixture by dividing the mass with the substance by mass in the solid mixture (from #1 above), then simply multiplying by simply 100.
