A. I won't work it but I'll give you the formula. 69.72=(67x) + (70(1-x)) x = 0.093 or 9.3 %

How to find percent abundance of 2 isotopes of an element?
Q. I am given two isotopes of the same element, I am given the atomic weight and mass number of each isotope. How would I find the percent of abundance for each isotope?
Asked by Brian - Wed Sep 17 15:54:02 2008 - - 1 Answers - 1 Comments
A. If you know the element, look up the atomic mass on the periodic table. It's the number with places after the decimal. If there are only two isotopes they have to add up to 100% (or in decimal form 1) so you set it up like this: (atomic weight of one isotope)(x) + (atomic weight of other isotope)(1-x) = the atomic mass you find on the table. Use algebra to find x. Don't forget to use the distributive property. Example: Cl-35 weighs 34.969 amu Cl-37 weighs 36.966 amu (34.969)(x) + (36.966)(1-x) = 35.453 (on the table for Chlorine) 34.969 x + 36.966 - 36.966 x = 35.453 -1.997 x = -1.513 x = 0.75764 so Cl-35 abundance is 75.764% and Cl-37 is 24.236 %

What factors make nitrogen gas the most abundance in earth atmosphere?
Q. Originally,Earth's atmosphere composition was not like today's.It is believed that the atmosphere started with methane as the most abundant.Later, the existence of ancient algae and other microorganisms made the atmosphere full of O2 until O2 was considered toxic then.The situation changed when the aerobic organisms evolved to reduce O2 composition to 21% of atmosphere.

How do you find the percent abundance when given the atomic mass?
Q. Specifically in the following problem: The element Boron exists as B-10 and B-11. The atomic mass of B-10 is 10.001 amu and the atomic mass of B-11 is 10.998 amu. If the average atomic mass of a mixed sample is given as 10.81 amu, what is the percent abundance of each isotope? I understand that the equation would be x+y=1, which would be 10.001x+10.998y=10.81 but I'm not sure how to continue. Many thanks!

For example if you know they are randomly distributed through a 1 mile square area you could take and measure the number in a 1/4 mile area and multiply that by 4. If you are not counting an individual again, then the percentage of error would be that individual divided by that individual plus the total population. Email me with the details.

A. It's not as simple as that - it depends on the kind of writing and what you're trying to achieve with the book. As a rule, if you don't need an adjective to build up a sufficiently vivid picture, don't use one. Don't use any word that you don't really need, in fact. Over-writing is a big problem for a lot of amateur writers. Also, be careful not to use two adjectives that mean the same thing. For instance, don't say 'his hair was messy and untidy' or 'the man was thin and skinny'. Well-chosen adjectives add to the story, but don't overdo it.

A. As far as I know, there is NO WAY for you to calculate the relative abundance of isotopes of a certain element. This data is determined experimentally. After you know the percentages, then the (weight average) Atomic Mass of the element may be determined by: AW (Element) = M(1) x f(1) + M(2) x f(2) + ... + M(n) x f(n) where M(1), M(2) ..M(n) are the atomic weights corresponding to isotopes 1, 2 ...n, respectively, and f(1), f(2) ... f(n) are the fractional composition (Percentage/100), relative abundance of each isotope. In your case the only thing you may say is that the isotope 28Si will have the highest abundance, since the final Atomic Weight is closer to 28.

So choose something meaningful to you -- that's the most powerful symbol! If it's living, take care of it. If it is inanimate, dust it, and maybe move it or change it on a regular basis. That will keep your purpose fresh in your mind. I live in Japan, but most of my feng shui is from Western books. I like Karen Kingston's Clear Your Clutter with Feng Shui book… [cont.]

Q. My teacher keeps using the word abundance in a lot of her questions but it doesn't seem to make sense. For example "Does the percentage by which the abundance of parent atoms changes during each trial approximately correspond to predicted by theory??" This question makes no sense to me!

What is the abundance of hydrogen, helium, ammonia, and methane on the earth?
Q. Please can anyone tell me what the abundance of these elements are on the earth.

A. Hydrogen = 0.5 parts per million in air @ sea level Helium = 5.2 parts per million in air @ sea level Ammonia = 0.0 Parts detected in air @ sea level. Methane = 2.0 parts per million in air @ sea level If you want to know how much is "on earth" in storage. I doubt there is an answer to that. Appros. 1/3 of the worlds oceans is hydrogen.
