Question

If 5.48 g of CuNO3 is dissolved in water to make a 0.840 M solution, what is the volume of the solution in milliliters?

Answer 1

Answer:

34.8 mL

Explanation:

First we convert 5.48 g of CuNO₃ into moles, using its molar mass:

• 5.48 g CuNO₃ ÷ 187.56 g/mol = 0.0292 mol

Now we can calculate the volume of the solution, using the definition of molarity:

• Molarity = moles / liters

• 0.840 M = 0.0292 mol / liters

• liters = 0.0348 L

Finally we convert L into mL:

• 0.0348 L * 1000 = 34.8 mL
