Answer: 633.6 g of
can be produced from the decomposition of 4.8 moles of 
Explanation:
The balanced chemical equation for decomposition of
is :
According to stoichiometry :
1 mole of
produce = 3 moles of 
Thus 4.8 moles of
will rproduce=
of 
Mass of 
Thus 633.6 g of
can be produced from the decomposition of 4.8 moles of 
Say the dereference between the two is that "Exo" means "outside" and "Endo" means "inside" meaning one pulls heat inside (endothermic) and the other expels heat (exothermic)
Hey there!
RbOH
Rb: 1 x 85.468 = 85.468
O: 1 x 16 = 16
H: 1 x 1.008 = 1.008
------------------------------------
102.476
The molar mass of RbOH is 102.476 g/mol.
Hope this helps!
Because it has a smaller atomic number. Elements are not lined up according to the higher average atomic mass, but rather according to the higher atomic number.
The answer is b. The sum of the individual gas pressure in the mixture
