Q
Q: What is the number of atoms in 2 moles of Na2SO4?
Solution:
Na2SO4 has 2 Na + 1 S + 4 O = 7 atoms. Number of atoms = moles x atoms per mole = 2 moles x 7 atoms = 14 atoms = 1.2044 x 10^24 atoms.
Steps: 6
Show Steps
Step 1: Identify the chemical formula of the compound, which is Na2SO4.
Step 2: Count the number of each type of atom in the formula: 2 Sodium (Na), 1 Sulfur (S), and 4 Oxygen (O).
Step 3: Add the number of atoms together: 2 (Na) + 1 (S) + 4 (O) = 7 total atoms in one formula unit of Na2SO4.
Step 4: Determine how many moles you have, which is given as 2 moles.
Step 5: Calculate the total number of atoms by multiplying the number of moles by the number of atoms per mole: 2 moles x 7 atoms = 14 atoms.
Step 6: If needed, convert the number of atoms to scientific notation: 14 atoms = 1.2044 x 10^24 atoms.
