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
