Sagot :
Answer:
2.06M NaCl
Explanation:
Molarity is defined as a ratio of moles of the solute (the substance you're dissolving) to Liters of solution (the volume of the finished solution). It uses the letter capital M as an abbreviation for the unit.
We're given values for both numbers (with the correct units already), so substitute, and calculate the number part:
[tex]\dfrac{n_{solute}}{V_{solution}}=\dfrac{3.09 [\text{mol NaCl}]}{1.50 [\text{L solution}]}=2.06\dfrac{[\text{mol NaCl}]}{[\text{L solution}]}=2.06[\text{M NaCl}][/tex]
