Question

you have 100 grams of each fuel. How many moles of each fuel do you have?
1. C3H8

2. C2H6O

3. C3H6O

Answer 1

Answer:

Formula of Mole is,

                               Mole = Mass / M.Mass

Mass is same for all compounds but M.Mass is different for all.

1. C₃H₈

                               Mole = 100 g / 44.1 g/mol

                               Mole = 2.27 moles

2. C₂H₆O

                               Mole = 100 g / 46.07 g/mol

                               Mole = 2.12 moles

3. C₃H₆O

                               Mole = 100 g / 58.08 g/mol

                               Mole = 1.72 moles
