Answer:
436.88 moles of P₄O₁₀
Explanation:
From the question given above, the following data were obtained:
Number of molecules of P₄O₁₀ = 2.63×10²⁶ molecules
Number of mole of P₄O₁₀ =?
From Avogadro's hypothesis,
6.02×10²³ molecules = 1 mole of P₄O₁₀
Therefore,
2.63×10²⁶ molecules = 2.63×10²⁶/6.02×10²³
2.63×10²⁶ molecules = 436.88 moles of P₄O₁₀
Thus, 436.88 moles of P₄O₁₀ are present in 2.63×10²⁶ molecules.
