Answer:
The mole is a key unit in chemistry. The molar mass of a substance, in grams, is numerically equal to one atom’s or molecule’s mass in atomic mass units.

I, m right?
Answer:
- Leaves impurities in their starting layer - Extraction
- Moves impurities from one layer to another - Wash
- Moves desired compound from one layer to another - Extraction
- Often involves a reaction in one of the layers - Extraction
- Leaves desired compound in its starting layer - Wash
Explanation:
Both extraction and wash are technical materials separation processes. Both seek to carry out a separation of liquid-liquid, through the relationship between solvent and solute present in this solution. Both use a separation funnel and are very similar processes where the main difference is the purpose that each one seeks to exercise. The extraction causes the dissolution of the material that the researcher wants to leave behind. this process leaves impurities in the initial solution layer and moves the researcher's desired compound to the second layer of solution. A chemical reaction can take place during this process.
A wash, on the other hand, dissolves all impurities from the solution and extracts the compound desired by the researcher. Therefore, we can conclude that during this process the impurities are moved from one layer to another in the solution until it is discarded from the funnel, leaving the desired compound in the initial layer.
NaOH (s) is in solid state and NaOH (aq) is an aqueous solution.
That new volume will be 0.25 L. You use the formula P1V1 = P2V2.
