What is the mass of oxygen in Fe2O3 when the formula mass of Fe2O3 is 160 amu?
In the formula Fe2O3, there are two iron (Fe) atoms and three oxygen (O) atoms. The molar mass of iron is approximately 56 amu, so the mass contributed by iron is 2 × 56 amu = 112 amu. Therefore, the mass of oxygen in Fe2O3 is the total formula mass (160 amu) minus the mass of iron (112 amu), which equals 48 amu. Thus, the mass of oxygen in Fe2O3 is 48 amu.
What is an amu and does it relate to atoms?
An atomic mass unit (amu) is a unit of mass used to express atomic and molecular weights. It is defined as a twelfth of the mass of an atom of carbon-12. Since atoms have very small masses, the amu is used to provide a more practical and meaningful scale for representing these minuscule values.
What is the molecular mass of P3S4?
To calculate the molecular mass of P3S4, we need to determine the atomic masses of phosphorus (P) and sulfur (S). The atomic mass of phosphorus is 30.97 amu, and the atomic mass of sulfur is 32.07 amu. Since there are three phosphorus atoms and four sulfur atoms in P3S4, we multiply the atomic masses and add them together: (3 x 30.97) + (4 x 32.07) = 327.74 amu. Therefore, the molecular mass of P3S4 is 327.74 amu.
What is the mass of a molecule with three carbon atoms?
The mass of a molecule with three carbon atoms (C) depends on the specific molecule. However, we can calculate an approximate mass by adding the atomic masses of the atoms. In the case of three carbon atoms, the approximate mass would be 3 times the atomic mass of carbon (12.01 amu), which equals around 36.03 amu.
What does a.m.u stand for?
Atomic mass unit. Unit for mass for atoms & their sub-atomic particles. An electron is rounded to 0 amu (since its mass is less than 1 amu). A proton and a neutron are 1 amu each.
What is the mass of 7.801018 carbon atoms?
how many moles of CF4 are there in 171 g of CF 4
How many number of neon atom in 300 amu of neon?
Devide mass by atomic mass to get 15 atoms Ne 300 (amu) / 20.2 (amu/atom Ne) = (14.9 atoms) = 15 atoms (= 303 amu)
How many Helium-atoms and Carbon-atoms do you have if you have He-atoms with mass of 40amu and C-atoms with mass of 120amu?
Mass of 1 Helium atom is 4 amu and mass of 1 Carbon atom is 12 amu. So there are 10 helium atoms and 10 carbon atoms

What units are used to measure the mass of atoms?
AMU=Atomic Mass Unit
What is the number of sulfur atoms that equal a mass of 32.07 amu?
One sulfur atom has an atomic mass of 32.07 amu. Therefore, to find the number of sulfur atoms that equal a mass of 32.07 amu, you would need just one sulfur atom.
What does adding s neutron to an atoms nucleus do to the atoms mass?
Adding a neutron to an atom's nucleus increases the atom's mass by approximately 1 atomic mass unit (amu), as neutrons have a mass of about 1 amu.
