Answer:
The answer is "10.84 g".
Explanation:
The formula for calculating the number for moles:

In the given acid nitric:
Owing to the nitric acid mass = 
Nitric acid molar weight
If they put values above the formula, they receive:


In the given chemical equation:

In this reaction, 2 mols of nitric acid are produced by 1 mole of water.
So, 1.204 moles of nitric acid will be produced:

We are now using Equation 1 in determining the quantity of water:
Water moles 
Water weight molar 


Answer:- B. Solvent molecules surround solute ions.
Explanations:- When an ionic solute that has positive and negative ions is dissolved in a solvent like water then the solute ions are surrounded by the water molecules in a way so that the highly electron negative oxygen atom of water is towards the positively charged ion of the solute and less electron negative which is hydrogen atom that has partial positive charge, surrounds the negatively charged ion of the solute.
Due to these forces made by the solvent molecules, the solute is broken into the ions and get dissolved in solvent.
