#"The final pressure of gas is 27 Pa."#

#"use the formula : "P_i/T_i=P_f/T_f#

#P_i:"initial pressure"#

#P_f:"final pressure"#

#T_i:"initial temperature"#

#T_f:"final temperature"#

#P_i=15" "Pa#

#P_f=?" "Pa#

#T_i=50 " "K^o#

#T_f=90" "K^o#

#"plug given values:"#

#15/50=P_f/90#

#P_f*cancel(5)cancel(0)=cancel(15)*9cancel(0)#

#P_f=3*9#

#P_f=27" "Pa#
