If element A has an atomic mass of 2 and element B has a mass of 3 what mass would be expected for compound AB?

In theory it should be 6 because AB is AxB (3x2) =6 But in practice it is more likely to be 2+3=5 if you are adding the masses

What element has 121.75 as it's atomic weight?
The element of Antimony (Sb) would have the atomic weight of 121.75.
What element has the atomic mass of 32.065?
Sulfur is a non meta element. Atomic mass of it is 32.065.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
How is the number of electrons is a neutral atom of a given element related to the atomic number of that element?
The atomic number tells you how many protons are in the element. The proton count is the same as the electron count as all elements have a charge of zero giving them the same. Simplified: the atomic number shows you how many electrons and protons are in the element. If it is a compound and it has a charge of +1 that means the element has lost one electron and has a positive charge. If it gained a electron it would be -1 as electrons are negatively charged.
What is the average atomic mass of phosphorus?

Is chlorine a element or compound or a mixture?
Chlorine is an element on the periodic table. If you look, its average atomic mass is 35.5 amus. It would be a compound if it was 'connected' with another element, ie Hydrogen. HCl is considered a compound, but chlorine (Cl) alone is just an element.
Is Ca a suspension solution mixture compound or element?
Ca is the chemical symbol for calcium, an element. It is an alkali metal with atomic number 20. ------------------------------------------- The above is true, however if the element Ca is present in a solution then it will be present as part of an Ionic compound in solution, note a solution is not a mixture, element or compound, it is a SOLUTION. An insoluble compound of Ca could be present in liquid, in which case you would have a suspension. A suspension is a mixture.
What element is in a black hole?
It is not expected that elements would survive as such, within a black hole. Gravitational force would crush everything together to the point where no atomic nuclei remain intact.
