Hey, here's the question:(adsbygoogle = window.adsbygoogle || []).push({});

"If a gauge reads -295mmHg where athmospheric pressure is 101.7 kn/m^2 and the vapor pressure is 2.8 kN/m^2, what is the absolute pressure?"

I converted the gauge pressure to 39.36 kN/m^2 but where do i go from here??!?! I know the equation is p_gauge= p_absolute - atmospheric, but where do I factor in the vapor pressure?!?!?!?!?!

Please help! Thank you :)
