If i hold a mole of material in my hand, it means that the weight of that material is equal to the molecular weight of that material; has 6.02E23 molecules in it and occupies a volume of 379.4 cubic feet at standard conditions of 14.7 psia and 60 deg F.

The first part is correct. If the numbers in the second part are correct, it is true only for an ideal gas. Other materials have various densities in their liquid and solid states.

Not exactly.
The first part is okay ... it will have the molecular weight and the number of atoms (or molecules).
However, the volume (at pressure and temperature) are specific to a certain material. If you don't be exact about what material you're talking about, you can't use the sentence.
For example, a mole of hydrogen (in its gaseous form) will occupy a LOT more volume than a mole of lead (in its solid form) at the same temperature/pressure condition.
