Answer:

#P_1 = 2.249atm#

Explanation:

The combined gas law is to be used
#(P_1V_1)/T_1 = (P_2V_2)/T_1#

Where P = pressure(in atm)
V = volume(in litres)
T = temperature in kelvin

convert the units to the appropriate units

#T_1 = 33^oC + 273K = 306K#

#V_1 = 774mL = (774mL)/(1000mL) = 0.774L#

#V_2 = 1229mL = (1229mL)/(1000mL) = 1.229L#

#T_2 = 51^oC + 273K = 324K#

#P_2 = 1.5atm#

Plug in the variables

#(P_1 xx 0.774L)/(306K) = (1.5atm xx 1.229L)/(324K)#

#(P_1 xx 0.774L)/(306K) = 0.00569#

#0.00253xxP_1 = 0.00569#

#P_1 = 0.00569/0.00253 = 2.249atm#
