Did I do this right?anyone please

I have to indicate which substance is a solvent and a solute.

a) A solution containing 10.0g of NaCI and 100.0g of water.
So I think solvent would be water and solute is NaCI.

b) A solution containing 20.0 mL of ethyl alcohol and 15. mL of water
I said Ethyl wold be solute and water solvent

c) A solution containing 0.50g of AgNO3 and 10.0 mL of water ( I said AgNO3 would be solute and again water solvent)

I think u've done right.
