<u>We are given:</u>

Mass of NaCl in the given solution = 22.3 grams

Volume of the given solution = 2 L

<u></u>

<u>Number of Moles of NaCl:</u>

We know that the number of moles = Given mass / Molar mass

Number of moles = 22.3 / 58.44 = 0.382 moles

<u></u>

<u>Molarity of NaCl in the Given solution:</u>

We know that Molarity of a solution = Moles of Solute / Volume of Solution(in L)

Molarity = 0.382 / 2

Molarity = 0.191 M

What is the degree of oxidation of a simple substance​​
marissa [1.9K]

Answer: The oxidation state of a free element (uncombined element) is zero. For a simple (monoatomic) ion, the oxidation state is equal to the net charge on the ion. For example, Cl– has an oxidation state of -1. When present in most compounds, hydrogen has an oxidation state of +1 and oxygen an oxidation state of −2.

hope this helps........ Stay safe and have a Merry Christmas!!!!!!!!! :D Explanation:

A children's liquid cold medicine has a specific gravity of 1.23. If a child is to take 1.5 tsp in a dose, what is the mass (in
julia-pushkina [17]

Assume 1 tsp is approximately can hold 5 mL liquid.

Given the dose of medicine = 1.5 tsp

Converting 1.5 tsp to mL:

1.5 tsp * \frac{5 mL}{1 tsp} = 7.5 mL

Given the specific gravity of the medicine = 1.23

That means density of the medicine with respect to water will be 1.23

As the density of water is 1 g/mL

We can take density of the medicine to be 1.23 g/mL

Calculating the mass of medicine in grams:

7.5 mL * \frac{1.23 g}{mL} =9.225 g

9.225 g medicine is present in one dose.
