0.06105 moles is the number of moles of water lost.
<h3>What is molar mass?</h3>Molar mass is defined as the mass in grams of one mole of a substance.
Given data:
Mass of water = 1.1g
Molar mass water = 18.016 g/mol
Moles of water =?
These quantities are related by the following equation;
Moles =
Substituting the values of the quantities and solving for moles, we have;
Moles = = 0.06105 moles.
Hence, the 0.06105 moles is the number of moles of water lost.

<h2>Answer:C</h2>
Explanation:
A chemical equation is a equation that describes a corresponding chemical reaction.
A chemical reaction is generally written as
→
refer to all the reactants involved in the chemical reaction.
Reactants are usually written on the left hand side of the chemical equation.
refer to all the products formed in the chemical reaction.
products are usually written on the right hand side of the chemical equation.
In the given reaction,,
are written on the right side of the equation.
So,,
are the products.
Answer:- 27.7 grams of are produced.
Solution:- The balanced equation is:
let's convert the grams of each reactant to moles and calculate the grams of the product and see which one gives least amount of the product. This least amount would be the answer as the least amount we get is from the limiting reactant.
Molar mass of = 207.2+2(126.90) = 461 gram per mol
let's do the calculations for the grams of the product for the given grams of each of the reactant:
=
=
From above calculations, NaI gives least amount of , so the answer is, 27.7 g of
are produced.
