What is the molality of a solution prepared by dissolving 75.8 g of ethylene glycol, HOCH2CH2OH, in 1.55 L of water? Assume the
GaryK [48]

Answer:

                     0.787 mol.Kg⁻¹   or    0.787 m

Explanation:

Data Given:

                  Mass =  m  =  75.8 g

                  Volume  =  V  =  1.55 L = 1550 mL

                  M.Mass of Ethylene Glycol  =  62.07 g/mol

                  Density of water  =  d = 1.0 g/mL

To Find:

                   Molality  =  <u>??</u>

Molality is a unit of concentration and is defined as the number of moles of solute per Kg of a solvent.

                    Molality  =  Moles of Solute / Kg of Solvent  --- (1)

First Calculate Moles of Solute as;

                    Moles  =  Mass / M.Mass

                    Moles  =  75.8 g / 62.07 g/mol

                    Moles  = 1.22 moles

Secondly calculate mass of water as,

                    mass of water  =  density × volume

                    mass of water  =  1.0 g/mL × 1550 mL

                    mass of water  =  1550 g or 1.55 Kg

Now, putting values of moles and mass of solvent in equation 1,

                    Molality  =  1.22 mol / 1.55 Kg

                    Molality  =  0.787 mol.Kg⁻¹   or    0.787 m

What is reacitivty series, and how you can access reactivity of metals...
lubasha [3.4K]

In Chemistry, a reactivity series of metals , also known as the activity series refers to the arrangement of metals in the descending order based upon their reactivity .

<u>Salient Features</u> :-

  • The metal at the top of the reactivity series are powerful reducing agents since they are easily oxidized.
  • The reducing ability of metals grows weaker while traversing down the series.
  • The electro-positivity of metals also reduces while moving down the reactivity series.
  • Metals that are placed higher on the reactivity series have the ability to displace metals that are placed lower in the series.

<u>The metal reactivity series is given below</u> :-

To access the reactivity of metal , from the given reactivity series identify any of the metal and locate the reactivity based upon the choice of reactivity. The metal at the top (Potassium) is most reactive and the metal at the bottom (Platinum) is the least reactive.
