Answer:
Explanation:
In one Ca(OH)₂ molecule, there are 5 atoms (1 Ca, 2 O and 2 H). This means that in 1.005x10²⁴ Ca(OH)₂ molecules, there are (5 * 1.005x10²⁴) 5.025x10²⁴ atoms.
To <u>convert molecules into moles</u>, we use <em>Avogadro's number</em>:
- 1.005x10²⁴ molecules *
= 1.6686 moles
Finally, we <u>convert moles into grams</u> using the <em>molar mass of Ca(OH)₂</em>:
- 1.6686 moles * 74.093 g/mol = 123.63 g
