Formula units??? im assuming moles 
if its how many moles of mgcl2 in 29.2g of mgcl2
to find moles: Mass / RFM = 29.2/95 = 0.307mol

if its the number of atoms: Moles x Avogadro contestant
0.307 x 6.02x10+23 

hope that helps

For the answer to the question above, I can't help you directly because I don't have a calculator right now. But I'll show you how to solve this.
<span>use the freezing point depression formula for this one: delta T = i * m * K where K is a constant, m is the molality (mol solute/kg solvent), and i is the van'hoff factor the van hoff factor is the number of ions that your salt dissociates into. Since it's an ALKALI flouride salt, how many ions? k is just a constant, you get it from a table in your textbook somewhere So you have everything to solve for the molality of the solution, once you did that, multiplying it by the mass of water to find the mols of the salt. Take the mass of the salt and divide by this mols to figure out the molar mass, and then compare it with the periodic table to identify the salt.
</span>
<u>Mole solute</u>   x  mass of Water  = Mol solute<u>
</u>kg Solvent

then 

Mass of solute  x  <u>            1             </u>   =  molar mass
                               mole of solute

How many bonds will an atom of bromine usually form in order to reach an octet of electrons?
irga5000 [103]

Answer:

So fluorine and bromine are halogens and when you work out the Lewis dot structure you'll see that they each have one unpaired electron, therefore these unpaired electrons join together to form one bond.

How many protons, neutrons, and electrons does cobalt-60 have? Is this a "normal" isotope of cobalt and how do you know?
liubo4ka [24]
Cobalt-60 has 27 protons (thus 33 neutrons). If an inter-nucleus neutron decays and emits an electron, this neutron transforms into a proton. Now we have 28 protons and 32 neutrons.
