Answer:
Impurities will be trapped in the crystals of the benzoic acid crystallized in this manner.
Explanation:
After benzoic acid is dissolved in hot water, it should have been allowed to cool gradually before it is transferred into an ice bath.
This gradual cooling will aid the separation of impurities so that when the vessel is now submerged in an ice bath, only pure benzoic acid is recrystalized.
If the vessel is immediately submerged into an ice bath, impurities will be trapped in the crystals of the benzoic acid.
Nothing is less dense than gas. gas is the least dense form of matter.
Answer:
2.857 × 10⁻⁴ M
Explanation:
First, we will calculate the molarity of the solution 1.
M = mass of solute / molar mass of solute × liters of solution
M = 0.5028 g / 879.9 g/mol × 0.100 L
M = 5.714 × 10⁻³ M
We can find the concentration of the final solution using the dilution rule.
C₁ × V₁ = C₂ × V₂
C₂ = C₁ × V₁ / V₂
C₂ = 5.714 × 10⁻³ M × 5 mL / 100 mL
C₂ = 2.857 × 10⁻⁴ M
