Problem 36

Calculate the mass in grams of each of the following samples. a. 1.21 moles of hydrogen sulfide b. 4.22 _ 10_3 moles of lithium sulfide c. 224 moles of ferric chloride d. 7.29 mmol of sodium carbonate (1 mmol _ 11000 mole) e. 8.14 _ 103 moles of sodium acetate f. 0.00793 mole of phosphine, PH3

Step-by-Step Solution:
Step 1 of 3

CRYSTALLIZATION:  Impure solid is dissolved at hot temperatures and then slowly crystallizes as solution cools  Impurities- unwanted substances 1. Solvent Selection: one that does not dissolve solid @RT but when heated, very soluble @BT and insoluble @RT 2. Dissolution: use boiling stick to stop bumping: overheating 3. De-Colorization: charcoal used to remove colored impurity 4. Gravity Filtration: collect solid impurities 5. Crystallization: - saturated solution: no more solute dissolved in solvent 6. Filtration: washing a solid: pour cold liquid over solid  Scratching inner wall of flask  Precipitation: different atoms combining into new molecule  Crystallization: molecule changing from o
