Answer:
2 moles of Methane gas will occupy 44.8 L
Explanation:
If one mole of any gas occupies 22.4 L under certain conditions of temperature and pressure, and those conditions are assumed in this question, then we comfortably solve this problem as follows;
1 mole of Methane gas ---------------> 22.4 L
2 moles of Methane gas -------------->?
Cross and multiply, 2 moles of Methane gas = 2 X 22.4 L = 44.8L
Therefore, 2 moles of Methane gas will occupy 44.8 L, if the conditions of temperature and pressure are maintained.
OPTION A IS THE RIGHT SOLUTION.
Answer:
<h2>6 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>6 J</h3>
