Question

What volume in mL of a 0.763 M solution of BaI2 would be required if you wanted 0.0131 moles of solute? _____ mL (Picture Attached)

Answer 1

Answer:

The right answer is V = 17.2 mL

Explanation:

• Knowing that the the relation between No. of moles and concentration:

No. of moles = C * V

where,

C is the concentration in morality and

V is the volume in liter

so you can calculate the volume using:

V = (No. of moles / C) = (0.0131 mol / 0.763 mol/L)

V = 0.0172 L

• Then yo need to convert the volume from Liter to milliliter

 V = 0.0172 L * (1000 mL / 1 L)

  V = 17.2 mL

So, the right answer is V = 17.2 mL
