inn [45]

Answer : The molarity of solution is, 1.73 mole/L

Explanation :

The relation between the molarity, molality and the density of the solution is,

where,

d=M[\frac{1}{m}+\frac{M_b}{1000}]

d = density of solution  = 0.876g/cm^3=0.876g/mL

m = molality of solution  = 2.41 mol/kg

M = molarity of solution  = ?

M_b = molar mass of solute (toluene) = 92 g/mole

Now put all the given values in the above formula, we get  the molality of the solution.

0.876g/ml=M\times [\frac{1}{2.41mol/kg}+\frac{92g/mole}{1000}]

M=1.73mol/L

Therefore, the molarity of solution is, 1.73 mole/L

Some chemical reactions releases energy other store energy what important chemical reaction storage energy?
olganol [36]

Answer:

A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart. This chemical reaction will release energy. In other words, it will be an exothermic reaction.
