How many grams of NaCl are in 2.0 Liters of a 3.0 M NaCl solution?

Chemistry
1 answer:
Naddik [55]3 years ago
4 0

Answer:

350.64g

Explanation:

So first you must know that M is mol/L

Next solve the problem using dimensional analysis

2L NaCl (3 mol/L) = 6 mol NaCl

After you got the number of moles you should look at your periodic table to find the molar mass

I see that it's 58.44g/mol

Use dimensional analysis again!

6 mol (58.44g/mol) = 350.64g

Write the ionic and half equation for H20.
Pavlova-9 [17]

2[H⁺] + [O²⁻] → H₂O

Explanation:

Half reactions are usually composed of components of oxidation-reduction (redox) reaction where one element is losing electrons while another is gaining so they can come together into a compound. The half-reaction shows part of a reaction where the combining elements are charged and the product, from the redox, is neutral.

In this case, the H⁺ is carrying the positive charge because it is donating an electron to O²⁻, which is the reason the O²⁻ is carrying the negative charge. Note that we need 2 H⁺ for every one O²⁻.  The O is being reduced while the H is being oxidized.
