How much is 50g versus 60ml?

Answer 1

The question isn't valid because a gram is a unit of mass but a milliliter is a unit of volume.

You would need to refer to a specific material's density to make a comparison. Density relates the volume of a material to its mass, but it can differ greatly based on the material in question. For example, 50g of lead occupies much less volume than 50g of water.
