Question

calculate the masses of potassium nitrate & H20 in 500g of 14% solution​

Answer 1

I hope my answer will help you

Answer 2

Given:

500g of 14% solution of KNO3 and H2O

To find:

Mass of KNO3 and H2O each

Solution:

14% solution means, 14g solute (KNO3) is present in 100g solution.

Thus, mass of water = 100-14=86g water

So in 500g solution, 14x500/100g

=70g KNO3 is present.

Mass of water present= 500-70= 430g.

Hence the mass of potassium nitrate & H20 in 500g of 14% solution are 70g and 430g respectively.
