Answer: There are 1.78 moles in 40.0 L of He gas at STP
Explanation:
According to ideal gas equation:
P = pressure of gas = 1 atm (STP)
V = Volume of gas = 40.0 L
n = number of moles = ?
R = gas constant =
T =temperature = (STP)
Thus there are 1.78 moles in 40.0 L of He gas at STP
The volume of Oxygen : 20,000 L
<h3>Further explanation</h3>Given
400 L : initial volume
150 atm : initial pressure
3 atm : final pressure
Required
Final volume
Solution
Boyle's Law
At a fixed temperature, the gas volume is inversely proportional to the pressure applied
Input the value :
V₂ = (P₁V₁)/P₂
V₂ = 150 atm x 400 L / 3 atm
V₂ = 20,000 L
