They have the same amount of particles.
If you convert 80g to moles, you will find that 80g of diatomic bromine is 1 mole.
<h2>Balance Chemical Equation</h2>
1. N2 + 3 H2 = 2 NH3
2. 2 KCIO3 = 2 KCI + 3 O2
3. 2 NaCI + F2 = 2 CI + 2 NaF
4. 2 H2 + O2 = 2 H2O
5. Pb(OH)2 + 2 HCl = 2 H2O + PbCl2
6. 2 AlBr3 + 3 K2SO4 = 6 KBr + Al2(SO4)3
7. CH4 + 2 O2 = CO2 + 2 H2O
8. C3H8 + 5 O2 = 3 CO2 + 4 H2O
9. 2 C8H18 + 25 O2 = 16 CO2 + 18 H2O
10. FeCl3 + 3 NaOH = Fe(OH)3 + 3 NaCl
11. 4 P + 5 O2 = 2 P2O5
12. 2 Na + 2 H2O = 2 NaOH + H2
13. 2 Ag2O = 4 Ag + O2
14. S8 + 12 O2 = 8 SO3
15. 6 CO2 + 6 H2O = C6H12O6 + 6 O2
16. 2 K + MgBr2 = 2 KBr + Mg
17. 2 HCl + CaCO3 = CaCl2 + H2O + CO2
18. HNO3 + NaHCO3 = NaNO3 + H2O + CO2 - already balanced
19. 2 H2O + O2 = 2 H2O2
20. 2 NaNO3 + H2SO4 = Na2SO4 + 2 HNO3
Mass %abundance # of atoms (pick 1000 sample)
68.9257 60.4% 604
70.9249 39.6% 396
*39.6* ( i got this by subtracting 100 as most percentage is out of 100)
*# of atoms* ( i just moved it one decimal place, then i am going to make the sample out of 1000, to get the decimal place)
Formula= total mass/ total #atoms
x= (68.9257u* 604) + (70. 9249*396)/ 1000
x- 69717. 3832/ 1000
x= 69.717amu or 69.72 amu
if you look on the periodic table the closet element with that mass is gallium ( amu is 69.72)
A component or constituent of a whole or one of the parts into which a whole may be resolved by analysis
