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. This number is known as Avogadro's number, which is approximately \(6.022 \times 10^{23}\).
Identify the quantity given in the problem: The problem states that we have 1.0 mole of glycine.
Apply Avogadro's number: Since 1 mole of any substance contains \(6.022 \times 10^{23}\) molecules, use this number to determine the number of molecules in 1.0 mole of glycine.
Set up the calculation: Multiply the number of moles of glycine (1.0 mole) by Avogadro's number \((6.022 \times 10^{23} \text{ molecules/mole})\) to find the total number of molecules.
Perform the multiplication: Calculate \(1.0 \times 6.022 \times 10^{23}\) to find the number of molecules in 1.0 mole of glycine.
