What is the atomic mass of a human?
The atomic mass of a human is the sum of atomic masses of all the elements that make up the body. On average, a human body is composed mostly of oxygen, carbon, hydrogen, and nitrogen, with trace amounts of other elements. The total atomic mass of a human is about 30 kilograms.
What is the atomic mass of starch?
The atomic mass of a starch molecule is calculated by adding up the atomic masses of all the atoms it contains. Since starch is composed of carbon, hydrogen, and oxygen atoms, the atomic mass can vary depending on the specific ratio of these atoms in the molecule. The average molecular weight of starch is around 162 grams per mole.
What is the atomic mass of gas?
The atomic mass of a gas depends on the specific element that the gas is composed of. For example, the atomic mass of oxygen gas (O2) is approximately 32 g/mol, while the atomic mass of hydrogen gas (H2) is approximately 2 g/mol.
What is the atomic mass of salt?
The atomic mass of salt, which is primarily made up of sodium chloride (NaCl), is the sum of the atomic masses of sodium (Na) and chlorine (Cl). The atomic mass of sodium is approximately 23 g/mol and the atomic mass of chlorine is approximately 35.5 g/mol. Therefore, the atomic mass of salt (NaCl) is approximately 58.5 g/mol.
A molecule of water is composed of two atoms of hydrogen and one atom of oxygen if the atomic mass number of hydrogen is 1 and the molecular mass of water is 18 the atomic mass of oxygen must be?
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
What element composed 75 of mass?
Arsenic has an atomic weight of 74,921 595.

The atomic mass equals what?
In science the basic unit is the atom which is composed of neutrons, protons, and electrons. Electrons are generally considered to small to count as part of the mass. Atomic mass is the sum of neutrons and protons. For example: Oxygen has 6 protons and, in its natural state, 6 neutrons. This means that its atomic mass is 12.
What is the atomic mass of gas?
The atomic mass of a gas depends on the specific element that the gas is composed of. For example, the atomic mass of oxygen gas (O2) is approximately 32 g/mol, while the atomic mass of hydrogen gas (H2) is approximately 2 g/mol.

What Atomic mass of Earth?
The atomic mass of Earth is not a standard measurement, as Earth is composed of various elements with different atomic masses. However, if you consider the average atomic mass of the elements that make up Earth, it can be estimated around 29 atomic mass units (amu), primarily due to the abundance of oxygen, silicon, and iron. This is a conceptual average rather than a precise figure, as the actual mass of Earth is approximately 5.97 × 10^24 kilograms.
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
What is the atomic mass of silver?
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
