    Thanks for this boss. You are a life saver.
    For example 4, it's easier if you look for the molar mass first
    then you look for the mass conc by dividing the gram by liter(obviously you convert if it's in ML)
    the 3rd step is to look for the molarity by dividing the result of your mass conc by the result of your molar mass(it has to be 284/142)
    you'll get 2 and you can multiply it by 2 then you'll get 4. Happy to help.

    On some occasions, you divided the solute mole into solvent litres/volume in order to find the Molarity, in another question you divided the solute mole into whole solution volume to find the molarity or concentration. What's the reason or factor for this?

    At 1:48, you said that we need to divide 2mol by 1 mole. So as at 3:10, why you did not multiply it with 2 and divided with 3? Because this isn’t the ration of moles between 2al and 3SO4 ?

  • @saifalsarker
    @saifalsarker 3 роки тому +1

    Excuse me! Concentration and molarity are two different terms. Concentration is the ratio of the mass of solute per liter solution and its unit is kg per meter cube.
    On the other hand, molarity is the ratio of the mole number of solute per liter solution and its unit is mole/Liter.

    For the last question why didn't we multiply the Na by 2 when we got 4M
    It is Na2 shouldn't we multiply it be 2 ? Na2= 4×2=8? Could you explain it to me please

    • @HarshYadav2004
      @HarshYadav2004 3 роки тому +1

      Bro 4M came bc we multiplied 2 by 2. The molarity of the solution in that case is 2 and in sodium sulphate , sodium has a subscript of 2 so we multiply the subscript by molarity (which equals to 2) and hence 2*2 equals 4

    • @cyclonevii_0
      @cyclonevii_0 Рік тому +1

      All you need to do is just multiply it by 1 mole of the compound by the amount of Na+ ions given. So : 1mol NaNO3 / 3 mol Na+. This will give you the molar concentration of the solute, or NaNO3.
