Describe how you would make 250 mL of 0.500 M HCI from 12.1 M HCI. Show calculations.

Question

John Wheeler · Accepted Answer

Using the dilution formula M1V1 = M2V2 you would use the following calculations.

((250 mL)x(0.500 M HCl))/12.1 M HCl
= 10.3 mL

This means you want to add 10.3 mL of the 12.1 M HCl into a 250-mL volumetric flask and then fill the rest with distilled water up to the etch line in the flask.

The materials used are as follows:tripple beam balance,evaporating basin,stop watch,HCL pellets,matches,candle, .weigh the empty basin on tripple beam balance and records the mass,then put hcl on evaporating basin,burn it until it change from blue to white,then put it again on tripple beam balance and records the mass,then calculate the mass of empty basin and that with hcl,state the sources of erros after experiments.this is how u can prepare 250 ML in 0.500 M HCL

The individual who put "Versace" is an answer is the pinnacle of comedic ability and should be lauded as such!

Gabi · Answer

My answer is 80 mL HCl. I used the dilution formula: 250 mL x .500 M HCl = "X" mL x 12.1 M HCl = 80 mL
