Answer:

#1650 "bar"# or #165000kPa#

Explanation:

Ideal gas law:
#PV=nRT#
Rearrangement:
#P=(nRT)/V#
Calculate amount of #"CO"_2#:
#n("CO"_2)=m/M=(14.0g)/(28gmol^-1)=2mol#
Convert temperature to Kelvin:
#T=75+273=348K#
Volume of container:
#V=3.5L#
Ideal gas constant:
#R=8.314L"bar "K^-1 mol^-1#
Substitute values into ideal gas law:
#P=(2molxx8.314L "bar " K^-1 mol^-1xx348K)/(3.5L)=1650 "bar (3 s.f.)"=165000kPa#
