What am I doing wrong!?

[gurusan]

I've got to complete this thingy for homework...I got every answer correct except this one. I am pretty sure I'm right and something is wrong with the system (you submit it online).

Can someone tell me if I'm right? this should be so easy!

If a vacuum gauge connected to a chamber gives a reading of 68 kPa where the local atmospheric pressure is given as 1.01325 bar, what is the absolute pressure in the chamber? Give your answer in Pa and correct to 4 significant figures in scientific notation eg 4.535e4 uses four significant figures but 4.5350e4 uses five.

Answer: 1.693e5 -------------- 0%
Units: Pa ---------------------- 20.0%
Score: 0.2/1


This is what I did to get the answer:
(kPa to Pa), (Bar to Pa)
68000+101325 = 169325 Pa

Because Absolute Pressure = Gauge Pressure + Atmospheric Pressure!!

In Sci Notation to 4 sig figs that's 1.693e5
