Question

Find the number of atoms in 5.296 moles of Na.

Answer 1

The number of atoms in 5.296 moles of Na can be found by multiplying the number of moles by Avogadro's number, leading to 3.19 × 10²´ Na atoms.

Step-by-step explanation:

To find the number of atoms in 5.296 moles of Na, we use Avogadro's number, which is 6.022 × 10²³ atoms/mol. The calculation is as follows:

• 
  
• Number of moles (n) = 5.296 moles
• 
  
• Avogadro's number (NA) = 6.022 × 10²³ atoms/mol
• 
  
• Number of atoms (N) = n × NA = 5.296 moles × 6.022 × 10²³ atoms/mol

The result is N = 5.296 × 6.022 × 10²³ atoms (we multiply the number of moles by Avogadro's number). Calculating this gives:

N = 3.19 × 10²´ atoms of Na
