Astack gas (before scrubbing, that is, before removing so2) has the following composition by mass: 6% so2, 22% o2, 72% n2. what are the mole fractions of each species in the stack gas?

Explanation:

Assume you have 100 g of the stack gas. Calculate the mass of each species in this sample according their percentages.

mass of sulphur : 6% of 100 g = 6 g

mass of oxygen : 22% of 100 g = 22 g

mass of nitrogen : 72% of 100 g = 72 g

Now calculate the number of moles of each species

number of moles of sulphur :

number of moles of oxygen:

number of moles of nitrogen:

Now to calculate the mol fraction of each we use the formula:

mol fraction of A =

Therefore

mole fraction of sulphur =

mole fraction of oxygen =

mole fraction of nitrogen =

answer; economic order quantity;

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
