Oil and Water
Answer:
10.24 ×10²³ molecules
Explanation:
Given data:
Mass of COCl₂ = 218.4 g
Number of molecules = ?
Solution:
Number of moles of COCl₂:
Number of moles = mass/molar mass
Number of moles = 218.4 g/ 129.84 g/mol
Number of moles = 1.7 mol
1 mole contain 6.022×10²³ molecules.
1.7 mol × 6.022×10²³ molecules / 1mol
10.24 ×10²³ molecules
