Question

6. a) Calculate the mass of sodium sulphate required to prepare 35% ( mass percent) solution in 200g of water. (b) How is fog different from smoke?

Answer 1

Answer:

Let the mass of sodium sulphate be required be x gram.

Mass of solution = x+200

where, x is solute.

35% = $\large\bf { \frac {x}{x+200} × 100}$

Now solve further.
