What does 3M HCl mean or compose of?

Answer 1

3M HCL indicates the concentration of the HCl (hydrochloric acid).

There are 3 moles of HCl dissolved in 1 litre of water

or

there is 109.5g (3 times the molecular weight) of HCl in 1 litre of water

Answer 2

HCl is the chemical formula of Hydrochloric acid. In essence, it is ONE hydrogen and ONE chlorine atom (H - Cl). the - signify a bond between the two atoms. HCL is thus called a molecule because it is made up 2 or more atoms.

3M means 3 Moles of HCl. this is suppose to tell you the concentration of HCl molecules in the liquid. concentration is how many molecules of HCl is in the liquid. one mole has 6.022×10^23 molecules. so that means that 3 M of HCl has 3*(6.022×10^23) HCl molecules in the liquid.

Answer 3

Rule of thumb: What you want (3M) over what you've got (12M) times how much you want of it. (3M/12M) * 100 ml = 25 ml of 12M. Suggest transfer 75 ml H2O into your flask and make up to the 100 ml mark with the 25 ml 12M HCl. Gives you 100 ml 3M HCl as required.

M1V1 = M2V2 Here you are solving for V1 V1 = M2V2/M1 = (3M * 100mL)/12M = 25mL Mix 25mL of 12M HCl with 75mL of water.

Answer 5

3M means there are three moles (a mole being 6.022×10^23 molecules) per litre of HCl.

Answer 7

it means 3 molecules of hydrochloric acid. it is compose of 3 molecules of hydrogen and 3 molecules of chlorine.

Answer 8

3 moles of hydrogen chloride (109.5 grams) dissolved per liter of water.

Answer 9

"HCl" is the scientific abbreviation for "Hydrochloric Acid." I'm not sure about the "3M".
