What is the atomic mass for carbon?
Its the atomic mass of carbon + the atomic mass of 3 oxygen. CO3 = C + 3(O) = 12.0107 + 3(15.9994) = 60.01
What atom has an atomic mass of 3?
Deuterium, which is an isotope of hydrogen, has an atomic mass of 3. It has one proton and two neutrons in its nucleus.
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
What is the atomic mass of lithium?
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
What is the atomic mass for carbon?
Its the atomic mass of carbon + the atomic mass of 3 oxygen. CO3 = C + 3(O) = 12.0107 + 3(15.9994) = 60.01
What atom has an atomic mass of 3?

What is the mass of 0.7891 mol of ferric oxide (Fe2O3)?
Atomic Mass of Fe: 55.8g/mol Atomic mass of O: 16g/mol Molecular mass of Fe2O3: 2(55.8)+3(16) = 159.6g/mol mass = Molecular mass x number of moles mass = 159.6g/mol x 0.7891mol = 125.94g
How many neutrons are in an isotope of lithium if it has an atomic mass of ten?
An isotope of lithium with an atomic mass of ten would have an atomic number of 3, meaning it has 3 protons. To find the number of neutrons, subtract the atomic number from the atomic mass: 10 (atomic mass) - 3 (atomic number) = 7 neutrons. Therefore, an isotope of lithium with an atomic mass of ten would have 7 neutrons.
What is the value of a pluss 3?
Plus 3.
What is the atomic mass of lithium?
The atomic number of lithium is 3. The only stable isotope of lithium has 4 neutrons. Therefore its relative atomic mass is 7.
What element is a nonmetal in period 3 atomic mass 12?
No element in period 3 has an atomic mass of 12.
What is the mass of atoms of sulfur?
The Atomic Mass of one (1) atom of sulfur is 37.02. The atomic mass of three (3) atoms of sulfur is 96.21. 32.07 * 3 = 96.21
What has a mass number of seven?
Lithium is an element with an atomic number of 3 and an atomic mass of 7.
Is the atomic mass of hydrogen 3?
The atomic mass of the most common form of hydrogen is 1. There are isotopes of hydrogen with a mass of 2 (deuterium) and 3 (tritium), but they are rare.
What is lithium atomic mass?
Naturally occurring lithium contains two isotopes. The common one has an atomic mass of 7. About one per cent of the lithium has an atomic mass of 6.The atomic mass of Lithium-Li is 6.941 grams.
What is the atomic mass number of hydrogen -3?
Hydrogen is a non meta element. Atomic mass of it is 2.
