Answer:
24dm³
Explanation:
Given parameters:
Mass of CO = 30g
Unknown:
Volume of CO at STP = ?
Solution:
To solve this problem, we need to find the number of moles of CO in the given mass.
Number of moles of CO =
Molar mass of CO = 12 + 16 = 28g/mol
Number of moles = = 1.07moles
Now;
1 mole of a gas occupies 22.4dm³ volume at STP
1.07moles will occupy 1.07 x 22.4 = 24dm³
Answer:
<h3>The answer is 8.00 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 we have
We have the final answer as
<h3>8.00 moles</h3>Hope this helps you
