The mass of polystyrene is easily estimated looking at its mass spectrum. The spectrum has the shape of a comb with a large number of teeth. Teeth are equally spaced. In the region between 1000 and 3000, the spacing is 104.12 g/mol. In the region between 3000 and 6000, the spacing is 104.18 g/mol. If the and the spacing is approximately 104.12 g/mol. The spacing changes

What type of plastic is a plastic disposable cup made of?
Polystyrene. the opaque white cups that you can make fingernails impressions in, are foamed polystyrene. Clear sups that you get on an airplane are general-purpose polystyrene.
What are the uses of polystyrene?
Food and dairy containers, produce baskets, fast food containers, closures and vending cups and lids comprise the biggest commercial market of polystyrene. Polystyrene is also used in the durable goods industry in the manufacturing of domestic appliances, toys, household goods, electronic goods and furniture. Because polystyrene is not susceptible to rough treatment it is favoured for use as packing materials. Polystyrene is used to protect goods that are shipped by stabilising the items inside the containers. Used for mail order due to its lightweight aspects, polystyrene doesn't add much to postage costs. The food industry uses polystyrene for climate control to keep produce fresh during transportation. Polystyrene is a common insulation product for walls, cavities, lofts and floors. Hope I helped :-)
Which is the best for insulation fibreglass or polystyrene?

Are polystyrene cup biodegradable?
Polystyrene cups are not biodegradable; they are made from plastic that can take hundreds of years to decompose in the environment. Instead of breaking down naturally, polystyrene can fragment into smaller pieces, contributing to plastic pollution. While some recycling programs may accept polystyrene, many areas lack the facilities to process it, leading to increased environmental concerns. Alternatives, such as biodegradable or compostable cups, are available for more sustainable options.
Is polypropylene better than polystyrene?
That depends on how you define "better" and what you're using it for.
Is 1 kg of sand heavier than 1 kg of polystyrene balls?
No, 1 kg of sand and 1 kg of polystyrene balls have the same weight because they both weigh 1 kilogram. The volume and density of the materials may differ, but in terms of weight, they are equal.
Is polystyrene biodegradable?
Polystyrene is NOT biodegradable
What is rigid polystyrene?
Rigid polystyrene is a hard plastic Rigid polystyrene is a hard plastic
Why is polystyrene called polystyrene?
Because polystyrene is the polymer of the monomer styrene; poli in the Greek language has the meaning of many.
What does the word polystyrene mean?
Polystyrene is a kind of hard plastic.
What is the other name for polystyrene?
The other name for polystyrene is Styrofoam.
What is polystyrene made?
Polystyrene is obtained by the polymerization of the monomer styrene.
What country is polystyrene from?
Polystyrene was discovered in Germany. Eduard Simon discovered it in 1839. He was from Berlin. Polystyrene is also called thermocole.
Why was methanol an appropriate solvent to precipitate polystyrene?
Methanol is used to force polystyrene OUT of solution. So the simple answer is: you can't. But, there is probably an extreme temperature or pressure that allows polystyrene to remain in solution with methanol present.
Compute the degree of polymerization of polystyrene?
The degree of polymerization(n) is the ratio between Molecular weight(M) and the molar mass of the repeating unit in a polymer(m). M=n*m The molar mass(m) of the monomer (styrene) is 104.15 grams/mol if you are given a Molecular weight, just devide by m, and you've got it!
