It may be that a gram of plutonium actually weighs a gram. But this stuff is, um, quirky. It likes to change phase, and that means a given volume of it will change volume - sometimes by as much as 25% or more. There are several allotropes of plutonium. What does this mean? Imagine trying to make a precise shape of this stuff so you could build, say, a weapon - and it changes volume on you in the middle of your work. Bummer. A change in volume is a change in density, but you knew that. Precalculaton of a weight of plutonium will have to take into account the differential densities (of the different phases) in some way so that the "workability" of this hazardous stuff can be optimized. The mechanism behind the phase changes is not completely understood. And with all these allotropes, and there are several of them, anyone fabricating anything with plutonium is going to have his hands full. Nothing like mixing it up, is there? No wonder we have to work at alloying the stuff to stabilize it as well as burn supercomputer time to model its behavior. A link is provided to the Wikipedia article on plutonium for further investigation.
The price is estimated at 4 000 $.
A gram of hydrogen has a greater volume than a gram of oxygen at the same temperature and pressure, as hydrogen has a lower molecular weight and therefore occupies more space per gram compared to oxygen.
The word gram is derived from the Greek gramma, meaning a small weight.
1 gram = 1 000 milligrams
Both a gram of gold and a gram of feathers have the same mass because weight is dependent on mass and gravitational acceleration. In this case, the mass is equal (1 gram), so they both exert the same amount of force on a scale, regardless of their differences in volume or density.
For the isotope plutonium-239: cca. 2,52.1021atoms.
Approx. 4 000 US $ for weapon-grade plutonium.
It costs $280 per gram, it is one of the most expensive elements.

The price of nuclear weapons grade plutonium is approx. 4 000 US $ for one gram, in 2010.
The cost of plutonium can vary greatly depending on factors such as purity and availability. However, a rough estimate would be in the range of tens of thousands to hundreds of thousands of dollars per gram.
One gram. A gram is a weight unit itself. 1000 grams make a kilogram.
One gram. A gram is already a unit of measurement for weight.

A gram is about the weight of a paper clip. A kilogram is about the weight of a kitten.
