what is the % mass/volume (%W/V)of KOH in 60ml of a solution that contains 5gn of KOH?
What is a gn? 5gn is 5 grams?
mass/v % = grams/100 mL soln
5/60 = ??
To calculate the % mass/volume (%W/V) of a solute in a solution, you need to divide the mass of the solute by the volume of the solution and multiply by 100.
In this case, you have 5 grams (gn) of KOH dissolved in 60 ml of solution. First, you need to convert the volume from milliliters (ml) to liters (L). There are 1000 ml in 1 L, so dividing 60 ml by 1000 gives you a volume of 0.06 L.
Next, divide the mass of KOH (5 grams) by the volume of the solution (0.06 L) and multiply by 100 to get the % mass/volume (%W/V):
%W/V = (mass of solute / volume of solution) x 100
= (5 g / 0.06 L) x 100
= 500 g/L
Therefore, the % mass/volume (%W/V) of KOH in the 60 ml solution is 500 g/L.
