Answer:
Explanation:
Hello,
In this case, since iron (III) chloride (FeCl3) and barium chloride (BaCl2) are both chloride-containing compounds, we can compute the moles of chloride from each salt, considering the concentration and volume of the given solutions, and using the mole ratio that is 1:3 and 1:2 for the compound to chlorine:
So the total mole of chloride ions:
And the total volume by adding the volume of each solution in L:
Finally, the molarity turns out:
Best regards.
Answer:
The wavelength of this light is 780.4 nm.
Explanation:
Given that,
The frequency of laser light,
We need to find the wavelength of this light.
We know that,
Where
is the wavelength of light
So,
So, the wavelength of this light is 780.4 nm.
Answer:
The answer is
<h2>2.64 g/mL</h2>Explanation:
The density of a substance can be found by using the formula
From the question
mass = 611 g
volume = final volume of water - initial volume of water
volume = 256.7 - 25.1 = 231.6 mL
The density of the metal is
We have the final answer as
<h3>2.64 g/mL</h3>Hope this helps you
