In seawater what is the solution? and in a cup of tea what is the solute and solution!

please help me 10 points best answer!!

Seawater is the solution; your question makes no sense. If you want to know what is the solvent and what is the solute in seawater, which I suspect you wanted to ask, the answers are water and sodium chloride.

A cup of tea is the solution; the solvent is water; the solute (materials dissolved) include tannins, caffein, sugar, and the like.

seawater is salt in water. But that doesn't mean 'Common salt, NaCl.' it contains other salts too, though in low amount. Seawater is 3% salt in 97% water. By weight.

Check the others' answers. They've already told you. I'll not repeat.
