Calculate the mass (in kg) of water produced from the combustion of 1.0 gallon (3.8 l) of gasoline (c8h18). the density of gasoline is 0.79 g/ml.

Hello!

Calculate the mass (in kg) of water produced from the combustion of 1.0 gallon (3.8 L) of gasoline (C8H18). The density of gasoline is 0.79 g/mL.

Let's balance the equation: 

Data:

m (mass) = ? (in Kg)

v (volume) = 3.8 L → 3800 mL

d (density) = 0.79 g/mL

MM (Molar Mass) of gasoline (C8H18)

C = 8*12 = 96 amu

H = 1*18 = 18 amu

--------------------------

MM (Molar Mass) of gasoline (C8H18) = 96 + 18 = 114 g/mol

Calculate the mass of gasoline:

Calculate the mass of water:  

If: m (mass), MM (Molar Mass), n (number of mols)  

Therefore:
