Molecules with large molecular weights will not have potential inhalation hazards.
It is because molecules that have large molecular masses will also have a high boiling point. Now boiling point and vapor pressure are inversely related. So the vapor pressure of such molecules will be very low. Hence, there will no vapors available for inhalation.
A high molecular weight will increase the effective resistance of the fabric. The better diploma of entanglement manner that will rupture, the more polymer bonds need to be broken, because of this, the polymer can take in more electricity earlier than failing. Excessive molecular weight will increase the chemical resistance - to some extent.
Hence, these will not cause inhalation hazards.

Answer:
pH = 6.80. The aqueous solution is slightly acid
If pH is 7.00 at 37°C, solution is neutral
Explanation:
2H₂O ⇄ H₃O⁺ + OH⁻ Kw = 2.4×10⁻¹⁴
To determine the pH of a solution, we must consider the [H₃O⁺]
[H₃O⁺] . [OH⁻] = 2.4×10⁻¹⁴
[H₃O⁺] = [OH⁻] → √2.4×10⁻¹⁴ = [H₃O⁺]
1.55×10⁻⁷ = [H₃O⁺]
pH = - log 1.55×10⁻⁷ = 6.80
pH = 7 → neutral
pH < 7 → acid
pH > 7→ basic
Equilibrium chemical reaction between chair and boat forms is:
Kc =
Suppose the total number of molecules is x
Number of molecules of chair form is 6.42/100 x
Number of molecules of boat form is 93.58/100 x
Kc =
= 14.6
