a) 2 moles of octane gives 16 moles of CO2.
1 mole of octane will give 8 moles of CO2
1.5 moles of octane will give = 1.5 × 8 moles of CO2.
Moles of CO2 formed = 12 moles CO2
b.) Number of moles = Mass / molar mass
Molar mass of H2O = 18 g/mol
In this reaction 18 moles of water are formed.
Mass of water formed = 18 × 18
= 324 grams of water.
C.) 25 moles of oxygen reacts to give 18 moles of water.
1 mole of water will be formed by 25/18 moles of oxygen
Number of moles = Mass / molar mass
Moles of water = 90 / 18
Moles of water = 5 moles.
Moles of oxygen required =( 25/18) × 5
Moles of oxygen required = 6.94 moles
