Answer:
2.11 ×10²⁴ atoms
Explanation:
Given data:
Number of moles of NaCl = 3.5 mol
Number of atoms = ?
Solution:
It is known that 1 mole contain 6.022×10²³ atoms. The number 6.022×10²³ is called Avogadro number.
3.5 mol ×6.022×10²³ atoms / 1 mol
21.1 ×10²³ atoms
2.11 ×10²⁴ atoms
Answer:
18.75 milligrams of active ingredient is the recommended dose for a child weighing 36–47 lbs .
