Ile wody potrzeba, żeby zgasić słońce?

No amount of water thrown on the sun would cause it to go out. Instead, any amount of water would cause the sun to burn even more. The burning of the sun is nuclear fusion, not chemical combustion. In nuclear fusion, the nuclei of atoms are pushed together so hard that they stick together and become new, heavier nuclei. While high temperature certainly plays a role in knocking nuclei close enough together that they experience fusion, the ultimate driver of nuclear fusion in stars is high pressure. To be more accurate, temperature and pressure are intimately linked, but it is ultimately the pressure in the star that creates the high temperature that drives fusion. This high pressure is caused by the star's own gravity. The more mass an object has, the more gravity it creates. This gravity pulls on everything, including the object itself. Simply put, a star is so massive that it gravitationally crushes itself to the point that its atoms fuse together.

Throwing water on the sun would simply increase the sun's mass, which would increase its gravity. This stronger gravity would crush the sun even more, leading to more nuclear fusion.
