Answer:
- 5.025x10²⁴ atoms
- 1.6686 moles
- 123.63 g
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
The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula
Putting the values in the equation
Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63
