Answer: P=1.63atm

Explanation:

Stp means standard temperature and pressure

Standard temperature = 273k

Standard pressure = 1atm

Using the formula

P1V1/T1=P2V2/T2

P1 = 1atm

V1=5.23L

T1=273k

P2=?

V2=3.45L

T2=293k

Substitute the values

1*5.23/273=p2*3.45/293

Cross multiply

293*1*5.23=p2*3.45*273

1532.39=941.85p2

P2=1532.39/941.85

P2=1.627

P2=1.63atm
