How much does a technetium atom weigh?
A technetium atom has an atomic mass of around 98 atomic mass units.
A mixture of NaCl and NaBr has a mass of 2.03 g and is found to contain 0.76 grams of Na What is the mass of NaBr in the mixture?
To find the mass of NaBr in the mixture, we first calculate the mass of Na in NaCl and NaBr combined, which is 0.76 g. Since NaCl contains one Na atom and NaBr contains one Na atom, this entire mass comes from Na in NaCl and NaBr. Therefore, the mass of NaCl is 0.76 g and the remaining mass of the mixture (2.03 g - 0.76 g = 1.27 g) is due to NaBr.
What is the gram atomic mass of hydrogen atom?
The gram atomic mass of a hydrogen atom is approximately 1 gram per mole.
What is the gram formula mass in NaCL?
The gram formula mass of NaCl (sodium chloride) is approximately 58.44 g/mol. This value is derived from adding the atomic masses of one sodium atom (22.99 g/mol) and one chlorine atom (35.45 g/mol) together.
What is the molar mass of sodium iodide?
The molar mass of sodium iodide (NaI) is approximately 149.89 g/mol. This can be calculated by adding the atomic masses of one sodium atom (22.99 g/mol) and one iodine atom (126.90 g/mol), which gives a total of 149.89 g/mol for sodium iodide.
What is the mass of calcium atom compared with the mass of helium atom?
The mass of a calcium atom is around 40 atomic mass units (u), while the mass of a helium atom is around 4 atomic mass units (u). Therefore, the mass of a calcium atom is 10 times greater than the mass of a helium atom.
What is mass of one atom of protactinium?
This mass is 38,36.10e-23 g.
What is the mass of a Methane atom?
16 g / mol
How much does a technetium atom weigh?
A technetium atom has an atomic mass of around 98 atomic mass units.
What is the mass of 1 mole of calcium atom?
40g
What is the molar mass of OH?
The molar mass of the hydroxide ion (OH-) is approximately 17 g/mol. This includes the combined mass of one oxygen atom (16 g/mol) and one hydrogen atom (1 g/mol) that make up the hydroxide ion.
What is the mass of an atom called?
Atomic mass and mass of an atom are somehow different from one another. Atomic mass of carbon will be 12. But mass of one carbon atom will be 1.992 x 10-23 g. As we say atomic mass as 12, it means that it will be 12 times as that of hydrogen atomic mass. If we say 12 g of carbon then it will be considered as gram atomic mass of carbon. Each gram atomic mass of an element will have 6.023 x 1023 number of atoms. 6.023 x 1023 is known as Avogadro's number. Gram atomic mass is also termed as one gram mole. So 6.023 x 1023 atoms weigh 12 g. Then one atom's mass ie mass of one atom will be 12/ 6.023 x 1023 = 1.9923626 x 10-23 g.
The mass of a hydrogen atom is 1.0 amu and the mass of a carbon atom is 12.0 amu What is the molar mass of methane CH4?
To find the molar mass of methane (CH4), sum up the atomic masses of all the atoms in the molecule: (1 hydrogen atom x 4) + (1 carbon atom) = 4 g/mol (hydrogen) + 12 g/mol (carbon) = 16 g/mol. Therefore, the molar mass of methane (CH4) is 16 g/mol.

How many times an atom of calcium is heavier than an atom of oxygen?
An atom of calcium is 2.5 times heavier than an atom of oxygen. This is because the atomic mass of calcium is 40.08 g/mol, while the atomic mass of oxygen is 16.00 g/mol.
