Answer:
As the temperature of a fixed volume of a gas increase the pressure will increase.
Explanation:
According to the Gay- Lussac's Law,
" The pressure of given amount of gas is directly proportional to the temperature at a constant volume"
Mathematical expression:
P ∝ T
P = CT
P / T = C
As the temperature increase, the pressure also increase.
The initial and final expression of volume and pressure can be written as,
P₁ / T₁ = P₂ / T₂
The answer is 4.45 × 10²⁴ units.
To calculate this, we will use Avogadro's number which is the number of units (atoms, molecules) in 1 mole of substance:
6.02 × 10²³ units per 1 mole
So, we need a proportion:
If 6.02 × 10²³ units are in 1 mole, how many units will be in 7.40 moles:
6.02 × 10²³ units : 1 mole = x : 7.40 moles
After crossing the products:
1 mole * x = 7.40 moles * 6.02 × 10²³ units
x = 7.40 * 6.02 × 10²³ units
x = 44.5 × 10²³ units = 4.45× 10²⁴ unit
You have to type in the answers as well so we have all the information.
