Question

How many mL of 12.0 M HČI are needed to

make 2.0 L of 0.10 M HCl solution?
1. 96 ml.
2. 15 ml
3. 67 ml
4. 17 ml
5. 120 ml.

Answer 1

17ml

Step-by-step explanation:

Since C1V1 = C2V2

where C1 = concentration of solution 1

V1 = volume of solution 1

C2 = concentration of solution 2

V2 = volume of solution 2

Converting 2 L to ml = 2*1000----> 2000ml

12.0*V1 = 2000 * 0.10

V1 = (2000*0.10)/12.0

=16.67ml ≈17ml

17ml

Hope this helps.
