# Seperation of your mixture of solids

п»їLaboratory 4: Splitting up of a Blend of Solids

Figures 1 to 4 here are not written out in your Lab Manual. They are really provided below to help you carry out your measurements more plainly.

1 ) Separating out the Iron:

Mass of Analyzing Dish: ___0. 6_______g

(Read every masses for the decimal places allowed by the balance/scale, typically one or two decimals, i. elizabeth. a 10th or a hundredth of a gram. )

Mass of Considering Dish as well as Solids Mixture: ____7. 5______ g

Mass of Hues Mixture: ___6. 9_______ g

Mass of Weighing Daily news: ___0. 7______g

Mass of Weighing Newspaper plus Iron: ____2. 6______g

Mass of Iron: ___1. 9_______g

Mass of Analyzing Dish: __0. 7________g

Mass of Considering Dish as well as Sand: ___2. 6_______g

Mass of Yellow sand: ___1. 9_______g

3. Isolating out the Benzoic Acid:

Mass of Daily news Cup (to be used in #4 below): __2. 5________ g

Mass of Filtering Paper: ____1. 1______g

Mass of Filtering Paper additionally Benzoic Acidity after finish drying: ___1. 9_______g

Mass of Benzoic Acid: _____0. 8_____g

Mass of Paper Cup in addition Sodium Chloride

following complete evaporation of normal water: ___4. 7_______g

Mass of Sodium Chloride

(use Mass of Paper Glass from #3 to calculate): ___2. 2_______g

Mass (g)

Percent in Mixture*

Iron filings

1 ) 9 g

1 . 9/6. 8*100= 28%

Sand

1 ) 9 g

1 . 9/6. 8*100= 28%

Table Sodium

2 . 2 g

installment payments on your 2/6. 8*100= 32%

Benzoic Acid

zero. 8 g

0. 8/6. 8*100= 12%

*Follow guidelines of calculations with Significant Figures

Estimate the Percent of each Substance (iron, crushed stone, salt, benzoic acid) in the Mixture by dividing the mass in the substance by mass with the solid blend (from #1 above), in that case multiplying by simply 100. That is,

% Material = (Mass of Substance / Mass of Sound Mixture) x 100
