What is the molecular formula of a substance that decomposes into 1.33 g of h and 21.3 g of o, and was found to have a molar mass of 34.1 g?

H2O2 First, let's determine how many moles of hydrogen and oxygen atoms we have. Start by looking up the atomic weights of those elements: Atomic weight hydrogen = 1.00794 Atomic weight oxygen = 15.999 Moles hydrogen = 1.33 g / 1.00794 g/mol = 1.319522987 mol Moles oxygen = 21.3 g / 15.999 g/mol = 1.331333208 mol We now have a ratio of 1.319522987 : 1.331333208 and we want a ratio of small integers that is close. Start by dividing all the numbers in the ratio by the smallest value, giving: 1 : 1.008950371 This ratio is acceptably close to 1:1 so I assume the formula is of the form HnOn where n is a small integer. Let's initially assume that n is 1, so the mass would be 1.00794 + 15.999 = 17.00694 Obviously 17 is far smaller than 34.1. So let's divide 34.1 by 17.00694 and see what n should be: 34.1 / 17.00694 = 2.005063815 So the formula we want is H2O2, which is hydrogen peroxide.

Polyethylene is a strong synthetic polymer that can be used to make toys and bottles. polyethylene is a plastic material called thermoplastic. one very useful property of thermoplastic is that when it is heated it turns into liquid, which can be molded into desired shape and size. also the material do not dissolve at room temperature.

The chlorine is the chemical property
