Joan needs a 0.053-M solution of HCl, but only has access to 2.12-M HCl, a 10-mL graduated pipet, and a 25-mL volumetric flask. How much HCl should she measure to create her desired solution

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.

Explanation:

Molarity of HCl Joan has access to =

Volume of 2.12 M of HCl Joan use =

Molarity of HCl Joan desired =

Volume of 0.053 M of HCl Joan can prepare =

Joan should measure 0.625 mL of 2,12 M HCl solution to create her desired solution.

h let me think

answer

i think the answer is a) as air pressure in an area increases, the density of the gas particles in that area decreases.

hope it
