There are eight moles of oxygen atoms  in 1 mole of Mn_{9}(ClO_{4}) _{2}.

<h3>What is the number of moles of oxygen atoms?</h3>

We know that a compound is composed of atoms. The atoms that make up the molecule are chemically combined. It is usual that the number of atoms in the compound would correspond with the chemical formula.

Now we have the compound  Mn_{9}(ClO_{4}) _{2}. In one mole of the compound we have;

  • 9 Moles of manganese atom
  • 2 moles of chlorine atom
  • 8 moles of oxygen atom

Thus, there are eight moles of oxygen atoms  in 1 mole of Mn_{9}(ClO_{4}) _{2}.

A 225-g sample of aluminum was heated to 125.5 oc, then placed into 500.0 g water at 22.5 oc. (the specific heat of aluminum is
Sidana [21]
when  heat gained = heat lost 

when AL is lost heat and water gain heat

∴ (M*C*ΔT)AL = (M*C*ΔT) water

when M(Al) is the mass of Al= 225g 

C(Al) is the specific heat of Al = 0.9 

ΔT(Al) = (125.5 - Tf) 

and Mw is mass of water  = 500g

Cw is the specific heat of water = 4.81 

ΔT = (Tf - 22.5) 

so by substitution:

∴225* 0.9 * ( 125.5 - Tf) = 500 * 4.81 * (Tf-22.5)

∴Tf = 30.5 °C
