The approximate mass is 11.
Technically you could express this in units of daltons as 11 Da (Daltons previously called amu, Atomic Mass unit, or as 11 (the dimensionless, relative atomic mass which chemists simply call atomic weight) .
The approximate mass of an atom that contains 10 protons and 11 neutrons is 21.
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
You can determine the approximate mass of an atom in atomic mass units by summing the number of protons and neutrons in the nucleus of the atom. The mass of a proton and neutron is approximately 1 atomic mass unit (amu), so the total mass of the atom would be the number of protons + number of neutrons in the nucleus.
When calculating the atomic mass of an atom, the mass of an electron is typically considered negligible. This is because the mass of an electron is almost 2000 times smaller than the mass of a proton or neutron, which are the primary components used in determining the atomic mass of an atom.
That has an atomic mass of (45 + 56), or 101.
The approximate mass of an atom that contains 10 protons and 11 neutrons is 21.
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
Bromine has an approximate atomic mass of 79.904.
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.

The mass of an atom is primarily determined by the protons and neutrons it contains since electrons have negligible mass. With 38 neutrons and an atomic number of 31 (which corresponds to the number of protons), this atom is likely a neutral atom of gallium. The approximate mass of this neutral atom can be calculated using the atomic mass of gallium (around 69.7 g/mol).
Mass number is a value approximate to the number of protons (Atomic Number) plus the number of neutrons within an atom of the element considered. I say approximate as mass number takes into account the mass of the nucleus and not the actual number of protons and neutrons in the nucleus.
This element has 26 neutrons, so its atomic number would be 26. Given an approximate atomic mass of 48 amu, this corresponds to the element iron (Fe).
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
An atom is the size of an orange compared to the Earth.
