3.95 L of sulfur dioxide is collected from the cumbustion of coal and is stored at 28.0C and 1.3 atm. How many moles of sulfur dioxide are present in the storafe vessel? How many grams of sulfur dioxide are present?
to find the moles …
(3.95 L / 22.4 L/mole) * (1.3 atm / 1 atm) * [273.15 ºK / (273.15 ºK + 28.0 ºK)]
multiply the moles by the molar mass to find grams
