Answer:The Atwood Machine is a device that demonstrates the basic principles of acceleration and dynamics. You'll mostly see Atwood machines in Physics laboratories and classrooms. It consists of two objects with different masses that hang vertically from a frictionless pulley that has a very small, negligible mass.
Explanation:
The balanced combustion reaction
for butane is;
2C4H10 + 13O2 → 8CO2 + 10H2O
Molar mass of water = 18.02
g/mol
Molar mass of oxygen = 32 g/mol
2.46g H2O(1 mol H2O/18.02g)(13
mol O2/10 mol H2O)(32g O2/1 mol O2) = 5.68g O2
