Sagot :
Answer:
The pressure of the gas=4.002 atm
Explanation:
We are given that
R=0.0821
Number of moles, n=15
Temperature, T=299 K
Volume of gas, V=92 L
We have to find the pressure of the gas.
[tex]PV=nRT[/tex]
Substitute the values
[tex]P\times 92=15\times 0.0821\times 299[/tex]
[tex]P=\frac{15\times 0.0821\times 299}{92}[/tex]
[tex]P=4.002 atm[/tex]
Hence, the pressure of the gas=4.002 atm
Answer:
According to the ideal gas law equation,
PV = nRT (here, P = 5.5 atm, V = 10L, T = 298K, R = 0.0821 atmL/mol K)
or, n = RT/PV = (0.0821 X 298)/(5.5 X 10) = 0.44 moles of He gas
