A chemical formula is a way of expressing information about the proportions of atoms that constitute a particularchemical compound, using a single line of chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs. A chemical formula is not a chemical name showing how the atoms are arranged.

What is the concentration of a solution formed by diluting 25.0 ml of a 3.2 M NaCl solution to 135.0 ml?

Irina-Kira [14]

Answer:

B) 0.59 M NaCl.

Explanation:

It is known that the no. of millimoles of NaCl before dilution = the no. of millimoles of NaCl after dilution.

∵ (MV) before dilution = (MV) after dilution.

∴ M after dilution = (MV) before dilution / V after dilution = (3.2 M)(25.0 mL)/(135.0 mL) = 0.5926 M ≅ 0.59 M.
