Question

You are asked to create a diluted solution of hydrochloric acid. Perform the necessary calculations to show how you would make 250mL of a 0.05M hydrochloric acid solution from a 12M stock solution. Show all of your work

Answer 1

0.05moles=1000ml

xmoles=250ml diluted HCl soln

xmoles=0.0125moles

0.0125moles=v1 of stock soln

0.0125*1000/12

v1=1.04ml

measure 1.04ml of stock solution and transfer it to 250ml volumetric flask and dilute to the mark.
