Depends on the size of the pinto bean.

5 grams
you dont water it that much. you put damp toilet paper in a jar and then the beans go on the inside sides of the jar so that you can see it grow, :D
It's by a process known as 'osmosis' Basically, the outer covering of the bean is water permeable, and the 'seed' inside the bean is porous. Water is absorbed through the outer membrane, which swells the 'pulp' of the seed, causing it to swell.
Alot as they get they sprout. I put enough water until it flowed out of the bottom of the pot.
