Thanks for asking us a question in Ask the Expert section of TopperLearning.com.
In case of multiple questions within a query, please post each question individually and let us know where you are getting stuck so that we would be able to explain things better.
Answer for Q. 1:
Srength of solution is given 20% means 20 g in 100 ml.
Or we can say 200 g in 1000 ml or 1 L.
The volume of solution containing 180 g of solute will be = 
Required volume = 0.9 L
