Is 5g of powder same as 5cc?

The answer is: no

5g of powder is not the same as 5cc. This is because the density of different powders can vary greatly. For example, 5g of lead powder would have a much smaller volume than 5g of polystyrene powder. Additionally, the shape of the powder particles can also affect the volume. For example, 5g of fine powder would have a larger volume than 5g of coarse powder.

Therefore, it is not possible to say definitively whether 5g of powder is the same as 5cc. It depends on the density and shape of the powder particles.
