What is the mass number for lithium?
Lithium is element #3. That, of course, is the atomic number - the number of protons. The atomic mass will of course depend on the specific isotope. The most common isotope is Lithium-7, that is, atomic mass = 7. Lithium-6 also occurs in nature as a stable isotope.
What is the mass of 3moles of oxygen?
The molar mass of oxygen is approximately 16 grams/mol. Therefore, the mass of 3 moles of oxygen would be 3 moles * 16 grams/mole = 48 grams.
What is the atomic mass of the mass for lithium?
The atomic mass of lithium is approximately 6.94 atomic mass units.
What is the percent 59.7 lithium mass of 100 g of the compound?
The percent mass of lithium in a compound with 100 g is calculated by dividing the mass of lithium by the total mass and multiplying by 100. So, if the compound contains 59.7 g of lithium, the percent mass of lithium would be (59.7 g / 100 g) * 100 = 59.7%.
What is lithium's molar mass?
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
Lithium mass number?
Lithium's mass number is 6.941.

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 atomic mass of lithium?
lithium is a metal element. Atomic mass of it is 6.941.
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 mass of lithium oxide made from 20g of lithium carbonate?
The mass of lithium oxide (Li2O) is 8,o9 g.
What is the atomic mass for lithium 3?
Lithium is a meta element. Atomic mass of it is 7.
Does the lithium get heavier after the reaction with oxygen?
When lithium reacts with oxygen, the mass of the lithium is unchanged. However, the mass of lithium oxide (Li2O) created is about 2.1 times as great as the starting mass of lithium metal (110% increase), due to the addition of oxygen. If the lithium reacts with nitrogen, the mass of lithium is similarly unchanged. The reaction produces lithium nitride (Li3N), with a mass about 1.7 times as great as the starting mass of lithium metal (67% increase), due to the addition of nitrogen.
How many atomic mass does lithium have?
Lithium is a metal element. Atomic mass of it is 7.
What is Atomic mass of lithium-6?
The atomic mass of lithium-6 is 6.941 amu
What is the molar mass of lithium selenide?
The molar mass of lithium selenide (Li2Se) can be calculated by adding the atomic masses of lithium and selenium together. The atomic mass of lithium is approximately 6.94 g/mol, and the atomic mass of selenium is approximately 78.97 g/mol. Therefore, the molar mass of lithium selenide is approximately 163.85 g/mol.
