I think it would be B hope not too late
A gauge records the pressure over atmospheric pressure (0kpa on the gauge is actually the atmospheric pressure and a reading of 276kpa is 276kpa over atmospheric pressure). That means that means that to find absolute pressure you just add atmospheric pressure (around 1atm (101kpa)) to 286kpa to get 387kpa. I hope this helps.
Answer:
Density = Mass / Volume. so, x = 90.5 g / 96 mL ... The Density would be 0.942 g/mL
