Hi, maybe im overlooking something but can someone explain this to me. Screen shot attached. The way I am looking at it is (.003 mol) x (22.4L/mol), mol cancels out and you get 67.2L or .0672mL. It is saying the answer is 67.2mL. Thank you!

It would be 0.003 Mol x 22.4L / mol= 0.0672L or 67.2 mL. Remember to change the significant figures.
