Answer to Question #249588 in General Chemistry for mas

Question

You wish to make a 0.284 M hydrochloric acid solution from a stock solution of 6.00 M hydrochloric acid. How much concentrated acid must you add to obtain a total volume of 175 mL of the dilute solution?

______________M

Answer 1

Solution

1L = 0.284 M of HCl$\frac{0.175L}{1L}\times0.284M$

=0.0497 M

$\frac{0.0497}{6.0M}\times1L= 0.008L$

= 8.283 mL

Volume of acid to be added is 8.283mL
