If one gram of gasoline releases 1.15,10⁴ cal of heat during combustion,
how much work can be done by burning 0.7 kg of gasoline?​

Answer:

Hello!

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:

I hope this helps! =)
