Answer:
<em>415.15 mL</em>
Explanation:
To solve the statement, you can use the law of Charles - Gay Lussac, which states that "<em><u>the volume of gas is directly proportional to its temperature at constant pressure</u></em>." Mathematically:
You can calculate the volume V₂ Clearing it from the equation and replacing the values granted by the statement to perform the calculation:
V₂ = V₁ x T₂ / T₁ = 222 mL x 56.1 ° C / 30.0 ° C = 415.15 mL
Therefore, <em>the gas at 56.1 ° C will occupy a volume of 415.15 mL</em>
Answer:
<h3>The answer is 149.83 moles</h3>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
N = 9.02 × 10^25 molecules of HCI
We have
We have the final answer as
<h3>149.83 moles</h3>Hope this helps you
