What is the volume of 0.10mole of a gas at STP
1 mol occupies 22.4 L at STP.
so .10 of a mole would be 2.24L of a mole of gas. How can I construct a cube that has that same volume.
Right. 2.24L is 2.24 x 1000 cc/L =
2,240 cc = 2,240 cubic centimeters.
You could take the cube root of 2240 to find the length of a side and measure card board squares of that length. Six sides (squares) taped together will be a volume of side x side x side = 2240 cc.
If you are doing this for a project, don't forget to think of the size. That will be the size of 0.1 mol of gas at STP. It will be 10 times larger for 22.4 L. That is much larger than most people think.
Is 22.4 bigger than 2.24?
To construct a cube with a volume of 2,240 cubic centimeters, you can follow these steps:
1. Take the cube root of 2,240 to find the length of a side. The cube root of 2,240 is approximately 13.78 centimeters.
2. Cut six cardboard squares, each with a side length of approximately 13.78 centimeters.
3. Tape the six squares together to form a cube.
The resulting cube will have a volume of approximately 2,240 cubic centimeters, which is equivalent to the volume of 0.10 moles of gas at STP. Keep in mind that this cube will be larger than most people expect due to the large volume of gas at STP.
