Calculate the molar mass that would be obtained from the actual experimental data under the following conditions. The unknown is methyl propyl ether (CH3OC3H7) which has a vapor pressure of 375.2 torr at room temperature, 20C. The volume of the flask is 135 ml, the temperature of the bath is 100C and atmospheric pressure is 760 torr. The average "molar mass" of air is 29.0 g/mol. (Hint: Draw a Diagram)"

I understand the rules for significant figures with multiplication/division, and adding/subtracting. But I am unsure of what to do when there is both multiplication and/or division, and adding and/or subtracting in the same question?
Calculate the pressure and the temperature of the compressed gas. In a diesel engine the compression ratios are typically much higher; redo the same calculation for the compression ratio of 20:1.
