Answer:
Approximately 352 liters of water vapor will be produced.
Assumption: the water vapor here behaves like an ideal gas.
Explanation:
Relative atomic mass data from a modern periodic table:
- Carbon: 12.011;
- Hydrogen: 1.008.
Burning methane in excess oxygen will produce carbon dioxide and water. The balanced equation will be
.
Hint: start by assign "1" to methane while balancing this equation.
How many moles of molecules in 108 gram of methane?
Molar mass of methane:
.
.
How many moles of water molecules will be produced?
Consider the ratio between the coefficient in front of water and that in front of methane in the equation:
.
.
Assume that water vapor here behaves like an ideal gas.
Ideal gas constant in liters and :
