Please help! What is the molarity of 450 mL of solution containing 15 g NaCl?

The answer to your question is 0.6 M

Explanation:

Data

Molarity = ?

Volume = 450 ml

mass of NaCl = 15 g

Process

1.- Calculate the molar mass of NaCl

NaCl = 23 + 35.5 = 58.5 g

2.- Calculate the number of moles of NaCl

             58.5 g of NaCl 1mol

                 15 g of NaCl   x

                         x = (15 x 1)/58.5

                         x = 0.26 moles

3.- Calculate the molarity

Molarity = moles/volume

-Substitutiion

Molarity = 0.26/0.45l

-Result

Molarity = 0.6 M

b. acid is the correct answer @jayxboof all social media

acid : acids are those which accepts an electron-pairs.

base : bases are those which donates ab electron-pairs.

alkali : it is a base that dissolves in water. it is basically a base and the ph greater than 7.

hydroxide ion : it is a poly-atomic ion which is negatively charged.

plasma is the state of matter where the substance is ionized and has no definite shape or volume. the fact of being ionized makes the substance a good electrical conductor.
