The number of moles of each atom present in 5 moles of Cu₃(PO₄)₂ are:
- 15 moles of Cu
- 10 moles of P
- 40 moles of O
<h3>Description of Cu₃(PO₄)₂</h3>
- 1 mole of Cu₃(PO₄)₂ contains
- 3 moles of Cu
- 2 moles of P
- (2×4) = 8 moles of O
<h3>How to determine the mole of each atom </h3>
The moles of atom present in 5 moles of Cu₃(PO₄)₂ can be obtained as follow
<h3>For Cu</h3>
1 mole of Cu₃(PO₄)₂ contains 3 moles of Cu.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 3 = 15 moles of Cu
<h3>For P</h3>
1 mole of Cu₃(PO₄)₂ contains 2 moles of P.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 2 = 10 moles of P
<h3>For O</h3>
1 mole of Cu₃(PO₄)₂ contains 8 moles of O.
Therefore,
5 moles of Cu₃(PO₄)₂ will contain = 5 × 8 = 40 moles of O

According to
Graham's Law of Diffusion,"the rates of diffusion of two gases are inversely proportional to the square root of their Molar masses or Densities at the same pressure and temperature".
r₁ / r₂ =
Where,
r₁ = Rate of Helium
r₂ = Rate of Oxygen
M₂ = Molar mass of Oxygen = 32 g/mol
M₁ = Molar mass of Fluorine = 4 g/mol
Putting values,
r₁ / r₂ =
r₁ / r₂ =
r₁ / r₂ =
2.82
Result:
Helium gas effuses
2.82 times faster than Oxygen gas.
Answer:
true
Explanation:
Rocks have different properties such as hardness and texture
Metamorphic rocks form when heat and pressure cause sedimentary or igneous rocks to recrystallize into new rock.
Soil is made up of dirt with decomposed organic material
The curved movement of air or water is the result of which of these:
The answer is B
