What is the atomic mass of curium?
IUPAC consider the atomic weight of curium 247; this is the mass of the isotope 247Cm, the curium isotope with the longest half life.
What is the atomic mass number of the curium?
The atomic number if curium (Cm) is 96 and its approximate atomic mass is (247). The () denotes that the exact mass is not confirmed, as curium is radioactive and unstable. So it is not easy to calculate the exact mass of all its isotopes.
What is what is uraniums atomic mass?
The atomic mass of uranium 238 is 238,050 788 247 ± 0,000 002 044.
How many neutrons does the most naturally occurring isotope of curium have in its nucleus?
Curium is an artificial chemical element. Number of neutrons = Atomic mass of an isotope - atomic number of the isotope The atomic number of curium is 96; and atomic mass is 247 so no of neutrons is 151.
Which element has a mass 100 less than cerium?
Isotopes of curium have masses between 232 and 252. It is your choice to subtract 1oo from (232 to 252) and to found an isotope. I have the same homework!!! The answer is calcium. - Linz The most important isotope of curium has an atomic weight of 247; 247-100 is 147. This is the mass of an important isotope of promethium.
How many moles of water are in 250.0ml of water?
Assuming a density of 1g/ml for water, 250.0 mls = 250 g250 g x 1 mol/18 g = 13.9 molesThe answer previously given (247 moles) is incorrect.
What is the atomic mass of curium?
IUPAC consider the atomic weight of curium 247; this is the mass of the isotope 247Cm, the curium isotope with the longest half life.
What is the atomic mass of berkelium?
The most stable isotope of berkelium - 247Bk - has an atomic mass of 247,070 307.
Mass number of uranium-238?
The atomic mass of 238U is 238,050 788 247 ± 0,000 002 044.
What is the element berkelium's atomic mass?
The most stable isotope of berkelium - 247Bk - has an atomic mass of 247,070 307.
What is the molar mass of uranium -238?
238 grams/mole The isotopic number is the approximate mass for any element. Such as if I say Carbon 14, the approximate mass is 14 grams/mole. If you are asking what is the mass of one atom of Uranium 238: Then you take the isotopic mass 238 grams/mole and divide by Avogadro's Number 6.022X10^23 atoms/mole this gives you units of grams/atom.
What is the mass number of uranium-235?
The atomic mass of uranium 238 is 238,050 788 247
The atomic mass and atomic number of berkelium?
The most stable isotope of berkelium - 247Bk - has an atomic mass of 247. The atomic number of berkelium is 97.
What is the reciprocal of -247?
The reciprocal of -247 is -1/247(Because -247 = -247/1
How do you write 247 percent as a fraction?
247% = 247/100
What is the atomic mass number of the curium?
The atomic number if curium (Cm) is 96 and its approximate atomic mass is (247). The () denotes that the exact mass is not confirmed, as curium is radioactive and unstable. So it is not easy to calculate the exact mass of all its isotopes.
What is the mass of uranium-238?
The atomic mass of the isotope uranium-238 is 238,050 788 247 ± 0,000 002 044 (Audi, Wapstra & Thibault-2003).
