Nylon 6,6 may be formed by means of a condensation polymerization reaction in which hexamethylene diamine [NH2-(CH2)6-NH2] and a

dipic acid react with one another with the formation of water as a byproduct. What masses of________(a) hexamethylene diamine and(b) adipic acid are necessary to yield 26 kg of completely linear nylon 6,6? This polymerization reaction occurs according to the following equation:

Answer:

Mass of hexamethylenediamine= 13,470.62 g

Mass of adipic acid =  16,940.13 g

Explanation:

Nylon -6,6 is synthesized by poly-condensation of hexamethylenediamine [NH₂-(CH₂)₆-NH₂] and adipic acid (C₆H₁₀O₄).

Both of these are taken in equal equivalents and reacted to form nylon 6,6 and by-product water is also formed.

Molecular mass of hexamethylenediamine [NH₂-(CH₂)₆-NH₂] =116.21 g/mol

Molecular mass of adipic acid (C₆H₁₀O₄) = 146.1412 g/mol

Molecular mass of Nylon 6,6 (C₁₂H₂₀N₂O₂) = 224.3 g/mol

Using unitary method :

Mass of hexamethylenediamine required for 26,000 g of Nylon 6,6 if 116.21 g/mol is required for 224.3 g/mol, is:

= \frac{26,000 *  116.21}{224.3}

= 13,470.62 g

Mass of adipic acid required for 26,000 g of Nylon 6,6 if 146.1412 g/mol is required for 224.3 g/mol, is:

= \frac{26,000 *  146.1412}{224.3}

= 16,940.13 g

Sunny_sXe [5.5K]

Answer:

its not that hard, i mean its a question that you kinda have to answer yourself. its basically asking you to write down the items that your family brought over the last week. just think of the things that your parents or family brought home. then you have to tell them what packaging was around the items, for example, plastic. and then etc.

Hope that helps you!

At any rate we have supplied the molecular formula as required.</span>
