C3H8 + 5O2 ==> 3CO2 + 4H2O
mols C3H8 = g/molar mass = = 2.2/44 = 0.05
Now use the coefficients in the balanced equation like this.
0.05 mols C3H8 x (5 mols O2/1 mol C3H8) = 0.05 x 5/1 = ?
mols C3H8 = g/molar mass = = 2.2/44 = 0.05
Now use the coefficients in the balanced equation like this.
0.05 mols C3H8 x (5 mols O2/1 mol C3H8) = 0.05 x 5/1 = ?
