16.99 g of silver nitrate are dissolved in water, then diluted to 500 ml what is the molarity of this solution

0.2M

Explanation:

First, we need to calculate the numbers of mol AgNO3 present in 16.99g. This is achieved as follows:

Molar Mass of AgNO3 = 108 + 14 + (16x3) = 108 + 14 + 48 = 170g/mol

Mass of AgNO3 = 16.99g

Number of mole = Mass /Molar Mass

Number of mole of AgNO3 = 16.99/170 = 0.1mol

Volume = 500mL = 500/1000 = 0.5L

Molarity =?

Molarity = mole /Volume

Molarity = 0.1/0.5

Molarity = 0.2M

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
