Answer:
<h2>0.05 moles</h2>
Explanation:
To find the number of moles in a substance given it's number of entities we use the formula
where n is the number of moles
N is the number of entities
L is the Avogadro's constant which is
6.02 × 10²³ entities
From the question we have
We have the final answer as
<h3>0.05 moles</h3>

Answer:
The Answer is 'D'
Explanation:
The diagram on the down side shows the behavior of the particles of a liquid so I suppose it is the ocean. While the top diagram shows the behavior of the particles of a gas so I am sure it's the air. Therefore I chose the last diagram because it describes exactly how you wanted in the question, which is the Ocean's water evaporating to become gas or the 'air' as we say

Answer:
0.83 mL
Explanation:
Given data
- Initial concentration (C₁): 12 M
- Final concentration (C₂): 1.0 M
- Final volume (V₂): 10.0 mL
We can calculate the initial volume of HCl using the dilution rule.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 1.0 M × 10.0 mL / 12 M
V₁ = 0.83 mL
The required volume of the initial solution is 0.83 mL.
