Answer: Option B) is the correct answer.

Explanation:

A polymer is defined as a molecule which has 'n' number of monomer units.

For example, (CH_{2}=CH_{2})_{n} is a poly ethene polymer.

Similarly, proteins are also polymers as they are made up of amino acids and contain number of repeated units just like polymers.

Thus, we can conclude that protein is made of polymers.

Help!!
anyanavicka [17]

I believe this a PV = nRT question whereas

you re write the formula and solve for volume

V = nRT/ P

then you input the values

P= pressure constant

V= x

n = moles = 0.2540

R = gas constant should be 8.314J mol

T = C degrees + 273.15 = K

solve for voume

make sure all units match

and use sig figs!!!!
