A carbon dioxide sample weighing 44.0 g occupies 32.68 L at 65°C and 645 torr. What is its volume at STP?
1 Answer
Its volume at STP is 28.09L.
Explanation:
We first need to find the volume of the
To do this, we can use the ideal gas law equation,
We should first convert our units to standard gas units.
We also need the moles of gas,
The ideal gas constant,
Substitute these values into the ideal gas law equation,
Rearrange for V:
We can call this the initial volume,
We can now use any of the gas law equations to solve the problem. Let's use Boyle's Law:
We can substitute in
Rearrange for
The final volume is 28.09L.
