Need Help!! Describe how to make 2.5L of 0.1M HCL solution from 12M HCL concentrated solution and water.
I got help earlier but still could not figure out the calculations. Please help, it has been a while since i took chemistry.

Thank you soo much

C'mon. I showed you how to do this, in fact, I did all but calculate it for you.
M x L = M x L
2.5L x 0.1M = ?L x 12M
?L = 2.5 x 0.1/12 = 0.0208
Take 0.0208 L(20.8 mL of the 12M HCL); place in a 2.5L volumetric flask, add water to the mark. That will give you 2.5L of 0.1M HCl. From your post it is unclear how many significant figures you have; therefore, that is up to you. If that is 2.50L, 0.100M, and 12.0M, then the answer is 20.8 mL.
