Question

How many molecules are in 25.8 moles of Co2

Answer 1

Answer:

1.55 × 10²⁵ Molecules

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
