What volume of solution is required to produce a 7.8M solution containing 23.6g of LiBr?
NARA [144]

Answer:

34.9 mL

Explanation:

First we <u>convert 23.6 g of LiBr into moles</u>, using its <em>molar mass </em>(86.845 g/mol):

  • 23.6 g ÷ 86.845 g/mol = 0.272 mol LiBr

Now we can <u>calculate the required volume</u>, using the <em>definition of molarity</em>:

  • Molarity = moles / liters
  • liters = moles / Molarity
  • 0.272 mol / 7.8 M = 0.0349 L

We can <u>convert L into mL</u>:

  • 0.0348 L * 1000 = 34.9 mL
