Answer:
0.38 mol
Explanation:
Given data:
Number of formula units = 2.3×10²³
Number of moles = ?
Solution:
According to Avogadro number ,
1 mole contain 6.022×10²³ formula units.
2.3×10²³ formula units × 1 mol / 6.022×10²³ formula units
0.38 mol
Thus, 2.3×10²³ formula units of NaCl contain 0.38 moles of NaCl.
