how many atoms of each element are in aluminum phosphate, AlPO4?

Question

anonymous · Answer

no idea

photon336 · Answer

We have aluminum = Al, P = phosphrous, and O = oxygen

photon336 · Answer

@ss44_ the elements in the compound are abbreviated. also the formula  shows you the number of atoms of each element.

photon336 · Answer

so we know that we have 1 aluminum atom and 1 phosphorus atom. how many oxygen atoms do we have?

anonymous · Answer

um im not sure is it 1 also?

anonymous · Answer

or is it 4?

photon336 · Answer

for oxygen it's 4. if there is no number written at the bottom then it's one atom. 

$$AlPO_{4}$$

@Photon336

photon336 · Answer

@ss44_ yes that's correct

photon336 · Answer

@ss44_ so all you have to do is look at the formula, it will tell you everything the type of elements  in the compound and how many elements there are. 

what about this molecule 

$$CH3CO2H $$
