What is 13 out of 100 as a percent?
13 out of 100 as a percent is 13%.
How much is 13 percent?
That depends what it is 13 percent of.
100 percent of 13 is what?
13 percent of 100 is 13.13% of 100 is 13.
What is 75 percent of 13 as a percent?
75% of 13 = 9.75 9.75 as a percent = 975%
How is 9 percent of 13 is 69.23?
9 percent of 13 is not 69.23 . 9/13 is approximately 69.23 percent. (rounded)
What the percent of carbon-12 and carbon-13 isotopes in nature?
Carbon-12 and carbon-13 are both stable isotopes of carbon. Carbon-12 makes up 98.89 percent of carbon in nature, while carbon-13 makes up only 1.1 percent of carbon.
How does the atomic mass of carbon show that it is an isotopes?
If your asking "how does the mass show there are isotopes", then the answer is this: Isotopes are found by using a mass spectrometer, and the abundance (percent amount) of each isotope is determined. Using this percent of abundance, the AVERAGE mass is reported on the periodic table. For example, if carbon 12 had mass of 12 and carbon 13 had mass of 13, but the percent abundance of 12 was 99% and the abundance of 13 was 1%, then the atomac mass would be 12*.99+13*.01=12.01 You can tell it has isotopes by seeing that the mass is a decimal and not a whole number. It is harder to tell with carbon, because it's only off by .01, but looking at chlorine it is more clear. Most isotope weights are very close to being whole numbers, like Cl35 mass is 34.98 and Cl37 is 36.97. But looking at Cl atomic weight, it is 35.45; the .45 tells you it is a average because the value lies between the whole numbers as a decimal. Cl is 35.45, which is an average of 35 and 37 that's 76% and 24% abundance respectively.
What gas has the percent of 0.038?
The abundance of carbon dioxide in the earth's atmosphere was 0.038% but is now nearer 0.04%.
How many C-13 atoms are present on average in a 13000-atom sample of carbon?
Carbon-13 make up 1.1% of carbon atoms. .011 x 19000 carbon atoms = 209 carbon-13 atoms present.
What is the percent yield for carbon disulfide if the reaction of 40.0g of carbon produces 33.0g of carbon disulfide?
This yield is very low - 13 %.
What is is the result when you total the individual relative abundance?
the result is 1.00, because relative abundance is just the percent abundance in decimal form. The percent abundance sum is 100%, therefore the answer is 1.00 because the decimal of 100% is 1.00
What is the percent abundance of cobalt in the universe?
Its percent abundance is 0%.* * Co60 has a relatively short half-life of 5.27 years, and so, is not found in nature at all. Therefore, its percent abundance is not relevant. It is produced artificially.
Where can carbon be found?
Carbon is found in abundance in the sun, stars, comets and atmospheres
What is percent abundance?
Take percent abundance times atomic mass for each isotope then add all up for average atomic mass.
How do you calculate the fractional abundance of Cl-37?
The fractional abundance is calculated by dividing the abundance of the isotope of interest by the abundance of all the isotopes of the element. For chlorine-37, the percent abundance is 0.2434, or 24.34%.
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
What is the natural abundance of Ag-107 is 51.84 percent What is the natural abundance of Ag-109?
48.16%
