Compressed air is used at the construction sites to drive nails and staples into the wood, but it requires workers to use cumbersome air hoses to supply the compressed air. A company developed new tool where a small amount of liquid fuel is injected into a chamber filled with air and then ignited, providing pressure that drives the nail. Products of combustion are then exhausted to the atmosphere. Calculate partial pressures of gases in the exhaust of the tool if 0.1 g of butanol is ignited in a chamber with the initial volume of 1.4 l at 1 atm. Exhaust temperature is 55 oC. Air contains 20% oxygen and 80% nitrogen.
