Answer:
1.55 × 10²⁵ Molecules
Step-by-step explanation:
We are given;
Moles of CO₂ = 25.8 moles
We are required to calculate the molecules of CO₂
We are going to use the Avogadro's constant, 6.022× 10²³,
Such that 1 mole of a compound contains 6.022× 10²³ molecules
Thus;
1 mole of CO₂ contains 6.022× 10²³ molecules
Hence,
25.8 moles will contain;
= 25.8 moles × 6.022× 10²³ molecules/mole
= 1.5537 × 10²⁵ Molecules
= 1.55 × 10²⁵ Molecules
Thus, 25.8 moles of CO₂ contains 1.55 × 10²⁵ Molecules
