Answer:
3843.96 × 10²³ atoms
Explanation:
Given data:
Mass of Li = 4430 g
Number of atoms = ?
Solution:
We will calculate the number of moles first.
Number of moles =mass/molar mass
Number of moles = 4430 g/ 6.94 g/mol
Number of moles = 638.32 mol
1 mole contain 6.022 × 10²³ atoms
638.32 mol × 6.022 × 10²³ atoms / 1 mol
3843.96 × 10²³ atoms
The soccer field has been placed with the outlines of the slaked lime. The chemical dust off from the falling has been calcium hydroxide.
<h3>What is slaked lime?</h3>
The boundary wall to the soccer or the other field has been marked with slaked lime powder. The chemical has the ability to react with bacteria and act as a disinfectant.
The slaked lime chemically is a white powder of calcium hydroxide. Thus, after falling on the soccer field, the chemical dusted off by Carla is calcium hydroxide. Thus, option A is correct.
