A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?
This atom has three neutrons. The atomic mass number is the sum of the protons and neutrons. All atoms of the same element have the same number of protons (lithium has three), so the neutrons have to account for the rest of the mass. 6 (the mass number)-3 (the number of protons in a lithium atom)=3. So this atom must have three neutrons.
An atom of carbon-12 is about twice as heavy has twice the mass as an atom of?
an atom of carbon-12 is about twice as heavy as an atom of oxygen-16.
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.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Experiment to determine the relative atomic mass of Lithium?
Lithium (Li) has the molecular formula weight of 6.94 grams per mole. Theoretically this would be the weight calculated by taking it in gas form at the Standard Temperature and Pressure of 273 degrees Kelvin and 1 atm, and a system volume of 22.4 liters.
The mass of a proton is 1.00727252 you The mass of a neutron is 1.008665 you What is the difference in the calculated and rest mass of an atom of lithium?
The rest mass of a lithium atom can be calculated by adding up the masses of its protons and neutrons. Lithium has 3 protons and 4 neutrons, so the calculated mass would be (31.00727252 + 41.008665 = 7.01600472 u). The rest mass of a lithium atom is approximately 7.016 u, so the difference between the calculated and rest mass is essentially zero.
Which Atom has the greatest mass between Lithium Sulphur oxygen and sodium?
lithium
The atomic weight of lithium is 6.941 amu What best describes what this value measures?
The atomic weight of lithium (6.941 amu) measures the average mass of an atom of lithium compared to 1/12 of the mass of a carbon-12 atom. It represents the sum of protons and neutrons in the nucleus of a lithium atom.
How much does a lithium atom weigh?
The mass of 0.100 mole of lithium is 0,6941 g. This can be calculated from this equation: m=n*M where m is mass in grams, n is amount of unit in mole and M is molar mas in gram/mole. the molar mass can be found in periodic table, for lithium it is 6,941 g/mol
A Lithium atom has an atomic mass of 6 How many neutrons does this atom have?

An atom of carbon-12 is about twice as heavy has twice the mass as an atom of?
an atom of carbon-12 is about twice as heavy as an atom of oxygen-16.
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 lithiums mass number?
The mass number of lithium is 7. This number represents the total number of protons and neutrons in the nucleus of a lithium atom.
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.
What is the mass defect formula used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons?
The mass defect formula is used to calculate the difference in mass between the nucleus of an atom and the sum of its individual nucleons. It is calculated by subtracting the actual mass of the nucleus from the sum of the masses of its individual protons and neutrons.
Explain the difference between atomic number and mass number?
Atomic number is the number of protons in the nucleus of an atom while the mass number is the sum of the protons and neutrons in the nucleus of an atom. for example lithium has an atomic number of 3 and a mass number of 7. Therefore lithium has 3 protons and 4 neutrons.
What is the percent composition of lithium in LiBr?
The percent composition of lithium in LiBr is approximately 7.0%. This is calculated by dividing the molar mass of lithium by the molar mass of LiBr and then multiplying by 100.
