Question

What volume in liters provides the following amounts of solute?

a) 0.100 mole of KCL from a 4.0 M KCL solution

b) 5.0 moles of HCL from a 6.0 M HCl solution


Explain in detail please...

Answer 1

a) 4 M KCl = 4moles KCl/liter

you need 0.1 moles

xliters * (4 moleKCl/liter) = 0.1 moles ==> x = 0.025 liters

b) 6 M HCl = 6 moles HCl/liter

you need 5 moles

xliters * (6 moles HCl/liter) = 5 moles ==> x = 0.833 liters

Answer 2

a. 0.1/4 litres
b. 5/6 litres
