AI Thread Summary
To convert 2.95 mol of Ba(OH)2 to atoms, multiply by Avogadro's number (6.022 x 10^23) to find the number of molecules, then multiply by the number of atoms per molecule (5 for Ba(OH)2). The calculation can be expressed as 2.95 mol x 6.022 x 10^23 molecules/mol x 5 atoms/molecule. For the mass of 3.01 x 10^23 formula units of strontium hydroxide, use the molar mass and Avogadro's number to find the mass. The process involves careful unit cancellation to ensure accuracy in calculations. Understanding these conversions is essential for solving similar chemistry problems.

2.95 mol Ba(OH)4 to atoms. (I think I wrote this problem wrong. It might be (OH)2 instead).
I'm confused >.< Do I:
1) multiply 2.95 mol by 6.02 x 10^23 atoms or
or
2) multiply 2.95 mol x 6.02 x 10^23 molcules x 9 atoms.
or is it something else?

Also, how do I do these?
Calculate the mass of 3.01 x 10^23 formula units (ions) of Strontium hydroxide.
Find the number of atoms in 16.0g of sulfur

Please help if you can. ~____~

moles is amount of particles. When this compound is broken down it is split into 1Ba and 4(OH) [according to you].

moles * 6.02E23= number of particles
(Number of particles)*(Number of particles the molecule can decompose to)=number of ions of that particular particle.
 
eax said:
moles is amount of particles.
hence no. of molecules=2.95*6.023*10^23
hence no. of atoms= no. of molecules*no. of atoms per molecule(9 in your case, though it is Ba (OH)2, i.e. 5):smile:
Strontium hydroxide is Sr (OH)2
hence no. of formula units= no. of atoms
hence mass = (molarmass/avogadro's no.)*no. of units
same for next.
refer University Chemistry by Bruce Mahan for details.
 
if they're asking for the atoms of Ba(OH)2 and not its constituent ions, then you would simply solve this by factor labeling

2.95mol Ba(OH)2(6.022x10^23 molecules Ba(OH)2/1mol Ba(OH)2) =?, you should verify that the units cancel out during such processes
 
I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
