A4,000 ml solution of agno3 contains 17.00 g of solute in water. calculate the molar concentration of the solution. 0.03 m 0.4 m 908 m 700 m

0.03 M

Explanation: Molarity  of a solution is number of moles of solute dissolved per liter of the solution.

where,

n= moles of solute

= volume of solution in ml = 4000 ml

Now put all the given values in the formula of molarity, we get

Therefore, the molarity of solution will be 0.03M.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

put the answers   and i could answer.
