Answer:

See the explanation below.

Explanation:

Multiply the percentage in decimal form of each gas by #"99000 kPa"#.

Nitrogen
#0.68xx99000color(white)(.)"kPa"##=##"67320 kPa"#

Oxygen
#0.23xx99000color(white)(.)"kPa"##=##"22770 kPa"#

Neon
#0.09xx99000color(white)(.)"kPa"##=##"8910 kPa"#

The sum of the partial pressures equals the total pressure 99000 kPa.

#"67320 kPa" + "22770 kPa" + "8910 kPa"="99000 kPa"#
