1. Answer: The molarity of given solution is 0.476 M.

Explanation:

Given : mass of sample (solute) = 7.0 g

Volume of solution (solvent) = 250 mL

Convert mL into L as follows.

Molar mass of NaCl is 58.44 g/mol. Hence, moles of NaCl are calculated as follows.

Molarity is the number of moles of a substance present in one liter of solution or solvent.

So, molarity of given solution is calculated as follows.

Thus, we can conclude that molarity of given solution is 0.476 M.
