- 5. The barometric pressure is generally given in units of inHg. Convert inHg to atm. Recall that 2.54cm = linch. Use dimensional analysis.An ore sample with a mass of 670 kg contains 27.7% of magnesium carbonate. If all of the magnesium carbonate in this ore sample is decomposed to form carbon dioxide, discuss how to determine what volume of CO2 is evolved in the process. What would have to be measured to predict the needed volume in advance? Please do not provide any numerical answers.(A). A sample of krypton gas at a pressure of 1.00 atm and a temperature of 24.3 °C, occupies a volume of 818 mL. If the gas is compressed at constant temperature until its pressure is 1.27 atm, the volume of the gas sample will be --------- mL. (B) A sample of neon gas at a pressure of 0.812 atm and a temperature of 29.8 °C, occupies a volume of 16.3 liters. If the gas is compressed at constant temperature to a volume of 5.59 liters, the pressure of the gas sample will be------------ atm.
