The sample of 15.0 g of KCl is dissolved into a solution with a total volume of 250.0 mL. What is the molarity of KCl in the sol
lina2011 [118]

Answer:

0.805 M.

Explanation:

Hello!

In this case, since the molarity of a solution is computing by dividing the moles of solute over the volume of solution in liters (M=n/V), for 15.0 g of potassium chloride (74.55 g/mol) we compute the corresponding moles:

n=15.0gKCl*\frac{1molKCl}{74.55gKCl}=0.201molKCl

Next, since the volume is 0.2500 in liters, the molarity turns out:

M=\frac{0.201mol}{0.2500L} \\\\M=0.805M

Best regards!

Which analogy can best be likened to the activation energy of a chemical reaction? a drain through which water flows a slide dow
Nina [5.8K]
Answer is: <span>a hill over which a wagon is pushed.
</span>For all chemical reaction some energy is required and that energy is called activation energy (<span>energy that needs to be absorbed for a chemical reaction to start)<span>.
There are two types of reaction: endothermic reaction (chemical reaction that absorbs more energy than it releases) and exothermic reaction (chemical reaction that releases more energy than it absorbs).
</span></span>R<span>eactions occur faster with a catalyst because they require less activation energy.</span>
