Verified step by step guidance1
Understand the concept of a mole: A mole is a unit in chemistry that represents a specific number of particles, typically atoms or molecules. One mole is defined as exactly 6.022 x 10^23 particles, known as Avogadro's number.
Identify the given information: You are given 68.6 moles of CO₂ and need to find the number of molecules in this quantity.
Use the relationship between moles and molecules: The number of molecules can be calculated by multiplying the number of moles by Avogadro's number. This is expressed mathematically as:
Substitute the values into the formula: Replace 'moles' with 68.6 and 'Avogadro's number' with 6.022 x 10^23 in the equation:
Perform the multiplication: Calculate the product of 68.6 and 6.022 x 10^23 to find the total number of molecules in 68.6 moles of CO₂.
