The formula mass of a molecule or an ion is?
The formula mass of a molecule or an ion is the sum of the atomic masses of all the atoms in the formula unit. This value is expressed in atomic mass units (amu) and is used to calculate the molar mass of the compound.
What formula will be use to get average atomic mass on an isotopes?

What is the formula mass of nitrogen monoxide in atomic mass units?
The formula mass of nitrogen monoxide (NO) is calculated by adding the atomic masses of nitrogen (N) and oxygen (O). The atomic mass of nitrogen is approximately 14 atomic mass units (amu) and the atomic mass of oxygen is approximately 16 amu. Therefore, the formula mass of NO is 14 + 16 = 30 amu.
The formula mass of neon is equal to its?
The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
What is the formula to get a number atomic neutron?
No. of neutrons=Atomic mass - Atomic number
What is relationship between the formula weight of a substance and its molar mass?
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
What is the relative formula mass of copper?
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.
To the nearest atomic mass unit what is the formula mass of aluminum oxide?
The formula mass of aluminum oxide (Al2O3) is approximately 102 atomic mass units.
The gram-formula mass of no2 is defined as the mass of?
The gram-formula mass of a compound is the sum of the atomic masses of all the atoms in a formula unit of the compound. For NO2, the gram-formula mass is calculated by adding the atomic mass of nitrogen (N) and two times the atomic mass of oxygen (O).

What is the formula mass of nitrogen monoxide in atomic mass?
The formula mass of a compound is the sum of the atomic masses of all the atoms in the chemical formula. For nitrogen monoxide, the chemical formula is NO. The atomic mass of nitrogen (N) is approximately 14.01 g/mol, and for oxygen (O) is approximately 16 g/mol. Therefore, the formula mass of nitrogen monoxide (NO) is approximately 14.01 + 16 = 30.01 g/mol.
What is the formula mass of CaSO4?
The formula mass of CaSO4 is calculated by adding the atomic masses of each element in the compound. Ca has an atomic mass of 40 g/mol, S has an atomic mass of 32 g/mol, and O has an atomic mass of 16 g/mol. So, the formula mass of CaSO4 is 40 + 32 + (4 x 16) = 136 g/mol.
