Approved Tutor Answer11 Months agoTo find out how many atoms are in 23 grams of sodium (Na), we first need to use Avogadro's number and the molar mass of sodium.
Understanding Molar Mass
The molar mass of sodium is approximately 23 grams per mole. This means that 23 grams of sodium is equivalent to 1 mole of sodium atoms.
Using Avogadro's Number
Avogadro's number is a constant that tells us how many atoms or molecules are in one mole of a substance. It is approximately 6.022 x 10²³ particles per mole.
Calculating the Number of Atoms
Since 23 grams of sodium equals 1 mole, we can directly use Avogadro's number:
- 1 mole of sodium = 6.022 x 10²³ atoms
Therefore, in 23 grams of sodium, there are about 6.022 x 10²³ atoms.
