Let’s suppose that potatoes (by weight) are 99% water and 1%, well,
potato!
If we take a 100 pound bag of potatoes out and put them in the hot June sun, the water will begin to evaporate. If we monitor the moisture content (which starts at 99%, of course) and we weigh the potatoes just when the moisture content gets to 98% (precisely), then
how much will the potatoes weigh at that moment?
How much will they weigh when the moisture content is 50%?
At first, the potatoe stuff is 1 pound (1% times 100 pounds) and the water is 99 pounds (99% times 100 pounds). At 98% water, the potatoe stuff is 2% weight, which is 1 pound, making the 98% weight (water) weight 49 pounds. Therefore, the combined wieght is 50 pounds.
When the water content is 50%, both weight the same, so since the potatoe stuff is 1 pound, so is the water. Therefore, the total weight is two pounds.
