Is a potato 50 percent water?
The potatoes are 99% water, so begin by finding 99% of 100 pounds to determine the weight of water beforehand. 99% of 100 is 99, so the potatoes are 99 pounds water and 1 pound potato matter. We need to determine how much the potatoes will weigh after dehydrating them to 98 percent water.

Which potato has the least water in it?
High-starch/low-moisture potatoes, such as russets or Idahos, generally lose their shape when simmered in soups or stews.
