PLEASE HELP ASAP

Question 5 You are making an industrial sized batch of beer. The vat you are using to make the beer has a depth of 19.2 m. The air pressure gauge you are holding, as you stand next to your brewI reads out 741 mmHg. A bubble forms, due to fermentation, at the bottom of the vat. The bubble rises to the surface. at which point its volume is 0.098 cm3. a} What is the absolute pressure at the surface of the beer {in Pa}? b} What is the absolute pressure at the bottom of vat (in Pa)? c) What was the volume of the bubble when it was at the bottom of the vat? (Give your answer in cmai [Assume the gas inside the bubble is ideal, the temperature of the beer is uniform, the contribution from the surface tension is negligible. and that beer has the same density as water]
