How many moles of CO2 , the carbon atoms

There would be 1 mole of C in CO₂

[AWK]

And in 58,68 g of CO₂?

[gigaimpact1]

And in 58,68 g of CO₂?

12/44*58.68=16

[AWK]

and moles of carbon atoms are?

[gigaimpact1]

and moles of carbon atoms are?

2?
So 2*16=32

[AWK]

No!
16 g C - how many moles of C

[gigaimpact1]

No!
16 g C - how many moles of C

So there is only one mole C, ok

[AWK]

16/12=1.333
So you have 1.333 mole of C atoms and 2 moles of H atoms ( from 1 mole of H2O).
Could you calculate an empirical formula of this hydrocarbon?

[gigaimpact1]

16/12=1.333

Oh sorry, so the moles of C is 1.333?

Oh! I brainfarted

[Burner]

You have '1.333' mole of C and 2 mole of H inside the compund. However, in empirical formula(and most other chemical formulas) the number of atoms must be in whole number. So, what would you do?

[gigaimpact1]

Balanced equation : 1 C₈H₁₂ + 11 O₂  4 CO₂ + 3H₂O

Mass of Carbon: 1.44 g
Mass of Hydrogen: 0.18 g
4 moles of Carbon
6 moles of Hydrogen
Empirical Formula: C₄H₆
Molecular Formula: C₈H₁₂

Is this correct?

[AWK]

Balanced equation : 1 C8H12 + 11 O2  4 CO2 + 3H2O

Balanced?

[gigaimpact1]

2 C₄H₆ + 11 O₂  8 CO₂ + 6H₂O

whoops

[AWK]

The molar mass of this hydrocarbon is between 50-60 g/mol.

[gigaimpact1]

C₄H₆ is 54 g/mol.
