Answer:

800 mg/ml

Explanation:

Recall that: 1 g = 1000 mg.

Hence

3.2 g of CaCl2 =  3.2 x 1000 = 3200 mg CaCl2

mass concentration of CaCl2 = mass of CaCl2/volume of water

                                   = 3200/4 (mg/ml)

                                   = 800 mg/ml

Therefore, the concentration (in mg/ml) of CaCl salt solution formed by dissolving 3.2g of CaCl2 in 4 ml of water is 800 mg/ml.

The concentration of calcium chloride solution will be 800 mg/ml.

The calculation of the concentration of CaCl₂:

Based on the given information,

  • The mass of CaCl₂ given is 3.2 grams.
  • The volume of water is 4 ml.

Now the concentration of CaCl₂ can be determined as,

Concentration = Mass/Volume

Now putting the values we get,

[tex]Conc = \frac{3.2 g}{4 ml} \\Conc = 0.8 g/ml\\Conc = 0.8 g * 1000 mg/ml\\Conc = 800 mg/ml[/tex]

Thus, the concentration of CaCl₂ is 800 mg/ml.
