Question

What MASS of NaCl are required to make 2.69L of a 0.14M solution?Use the correct abbreviation for the UNITS

Answer 1

To solve this problem, let's use the definition for molarity:

Replacing the values of the problem:

Now, to find the mass, we multiply by the molecular weight of NaCl. (Which is about 58.44g/mol)

The answer is approximately 22.2g of NaCl
