to convert m into km we have to divide it by 1000.so,
9426/1000=9.426km
92.2km+9.426km=101.626km.
As,
5471 kJ heat is given by = 1 mole of Octane
Then,
5310 kJ heat will be given by = X moles of Octane
Solving for X,
X = (5310 kJ × 1 mol) ÷ 5471 kJ
X = 0.970 moles of Ocatne
So, 0.970 moles of Octane will liberate 5310 kJ energy. Now changing moles to mass,
As,
Moles = mass / M.mass
Or,
Mass = Moles × M.mass
Putting values,
Mass = 0.970 mol × 114.23 g/mol
Mass = 110.83 g of Octane
Answer: density equals 3 g/mL
Step by step explanation:
D=m/v
D=45/15
D=3
The potential energy of the products is higher than the potential energy of the reactants.
