2015年11月8日 · The Mass Number is the mass of a particular atom individually and is measured in Atomic Mass Units (AMU); these will always be whole numbers. The most common Isotope is found by rounding the Weighted average found on the periodic table to the nearest whole number. In this case Oxygen has a Weighted Average Atomic Mass of 15.999 AMU.

The atomic mass unit is used to express the atomic mass of the atom. It is equivalent to the 1/12th mass of the carbon-12. The atomic mass unit of Oxygen is 16 u

Atomic mass of oxygen=16g. mass of 1 mole of atom= mass of $$ 6.0223\times 10^{23} $$ (Avogadro's no ...

1 mol oxygen atom contains 6.023 × 10 23 = 16 g Mass of ⇒ 6.023 × 10 23 oxygen atoms = 16 g Mass of 1 atom of oxygen = 16 g 6.023 × 10 23 = 2.66 × 10 − 23 g

2018年4月24日 · Relative atomic mass also equals to a atom's molar mass which is defined as the mass of one mole of that atom. In this, one mole of oxygen atoms weigh #16g# . Hence two moles weigh #16g *2 = 32g#

Not to be confused with the mass number, the atomic mass is the mass of an entire atom, including its protons, neutrons and electrons. For example, the atomic mass of oxygen is 16 amu (atomic mass unit).

2023年11月21日 · Oxygen has three isotopes: oxygen-16, which has an atomic mass of 15.994915 amu and a natural abundance of 99.757%, oxygen-17, which has an atomic mass of 16.999132 amu and a natural abundance of ...

2017年12月2日 · Of course, we know that oxygen, as are most of the elemental gases, is binuclear, i.e. #O_2#, but here we were asked for the atomic mass not the molecular mass. Answer link Related questions

The atomic mass of an oxygen-18 atom is 18 atomic mass units. The 18 in the isotope name indicates the mass number of the atom which is the total... Become a member and unlock all Study Answers

Why oxygen was initially considered as a reference for atomic mass? It has lower mass; It reacted with large number of elements and formed compounds; This atomic mass unit gave masses of most of the elements as whole numbers; Both B and C
