HUNDRED GRAMS too because of the law of conservation of mass. The law of conservation of mass states that mass is neither created nor destroyed. So both sides will have the same mass
Answer:
5
Explanation:
they are all significant All non-zero numbers ARE significant
One mole of a substance contains 6.02 × 10∧23 particles. Thus we first convert 89.2 g to moles. 1 mole of sodium contains 23 g
Hence 89.2 g = 89.2 / 23 g = 3.878 moles
Therefore, 3.878 × 6.02×10∧23 particles= 23.346 × 10∧23 particles
Hence 89.2 g of sodium contains 2.335 ×10∧24 particles
A seperation method that would be most successful woth the separation of a salt and water mixture would be evaporation for these reasons, (1) There are no magnetic elements involved with salt nor with water, (2) Observing colour differences would not have much affect on separating the two, and (3) Chromatography is used to separate two liquids, such as speparating two dyes, not salt and water.
Evaporation:
The water will evaporate, leaving you with salt as a solid.
