Q
Q: What is the number of atoms in 2 moles of NaCl? (2044)
Solution:
Each NaCl unit has 2 atoms (Na and Cl). Therefore, 2 moles of NaCl contain 2 x 6.022 x 10^23 x 2 = 1.2044 x 10^24 atoms.
Steps: 5
Show Steps
Step 1: Understand that 1 mole of any substance contains 6.022 x 10^23 units of that substance. This number is called Avogadro's number.
Step 2: Recognize that each unit of NaCl (sodium chloride) is made up of 2 atoms: one sodium (Na) atom and one chlorine (Cl) atom.
Step 3: Calculate the total number of NaCl units in 2 moles. Since 1 mole has 6.022 x 10^23 units, 2 moles will have 2 x 6.022 x 10^23 units.
Step 4: Now, since each NaCl unit has 2 atoms, multiply the total number of NaCl units by 2 to find the total number of atoms.
Step 5: Combine the calculations: 2 x 6.022 x 10^23 x 2 = 1.2044 x 10^24 atoms.
