Best regards.
Sea fossils were found on top of the mountains which gave evidence of evolution for continents and oceans
Answer: 0.0624 atm
Explanation:-
According to the ideal gas equation:

P = Pressure of the gas = ?
V= Volume of the gas = 45.0 L
T= Temperature of the gas = -10.0°C = 263 K 
R= Gas constant = 0.0821 atmL/K mol
n= moles of gas
Moles of gas=

The pressure of sulfur hexafluoride gas in the reaction vessel after the reaction is 0.0624 atm
