What is the molarity of 6 moles (mol) of NaCl dissolved in 2 L of water?
Mama L [17]

Answer:

C:  \frac{6 mol}{2 L}

Explanation:

we can use the molarity equation

M = \frac{mol}{L}

so to find M we plug in what we know, which is 6 moles of NaCl and 2 L of water, which gives us:

\frac{6 mol}{2 L}

Discribe how to prepare 50.00mL of a 3.00M hydrochloric acid solution using 12.0 M HCl.
Leokris [45]

Answer:

The answer to your question is given below.

Explanation:

To prepare 50mL of 3M HCl, we must calculate the volume of the stock solution needed. This can obtained as follow:

Molarity of stock solution (M1) = 12M

Volume of stock solution needed (V1) =?

Molarity of diluted solution (M2) = 3M

Volume of diluted solution (V2) = 50mL

The volume of the stock solution needed can be obtained by using the dilution formula as shown below:

M1V1 = M2V2

12 x V1 = 3 x 50

Divide both side by 12

V1 = (3 x 50)/12

V1 = 12.5mL

The volume of the stock solution needed is 12.5mL

Therefore, to prepare 50mL of 3M HCl, we must measure 12.5mL of the stock solution i.e 12M HCl and then, add water to the mark in a 1L volumetric flask. Now we can measure out 50mL of the solution.

When a sodium (Na) atom forms an ion so that it looks like a noble gas with a full valence shell, what will its charge be?
Setler79 [48]

Answer:

I believe 1+

Explanation:

when Na loses 1 electron in the outer shell it has 8 valence protons on it's new most outer shell. so now it has 11 protons and 10 electrons. that extra proton (positively charged) adds one extra charge. so +1
