What is the pressure in a 5 L tank with 1.5 moles of oxygen at 39.3 degrees Celsius?

The pressure in the tank is 7, 6 atm

Explanation:

We convert the unit of temperature in Celsius into Kelvin:

0°C= 273K --> 39,3°C= 39,3+ 273= 312,3 K

We use the formula:

PV=nRT ---> P =nRT/V

P= 1,5 mol x 0,082 l atm/K mol x 312,3 K/5 L

P= 7,68258 atm

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
