Answer:
Such molecule must have molecular formula of C15N3H15
Explanation:
Mass of carbon in such molecule
The atomic mass of carbon is 12.01 g/mol, so in 182.28 g of carbon there is 15.18 mols of carbon.
Mass of Nitrogen in such molecule
The atomic mass of nitrogen is 14.01 g/mol, so in 42.53g of nitrogen there is 3.04 mols of nitrogen.
Mass of Hydrogen in such molecule
The atomic mass of Hydrogen is 1.00 g/mol, so in 15.19 g of Hydrogen there is 15.19 mols of Hydrogen.
Such molecule must have molecular formula of C15N3H15
The composition of the stack gas are :
= 0.8713
= 0.0202
CO = 0.107
<h3 /><h3>What is a mole fraction?</h3>The ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the components.
Assuming 100 g of the stack gas. Calculate the mass of each species in this sample according to their percentages.
Mass of : 70% of 100 g = 70 g
Mass of : 15% of 100 g = 15 g
Mass of CO : 15% of 100 g = 15 g
Now calculate the number of moles of each species:
Number of moles of :
= 4.3 mole
Number of moles of :
= 0.10 mole
Mass of CO : = 0.53 mole
Now to calculate the mole fraction of each we use the formula:
Mole fraction of :
= 0.8713
Mole fraction of :
= 0.0202
Mole fraction of CO : = 0.107
Hence, composition of the stack gas are:
= 0.8713
= 0.0202
CO = 0.107
