How does %T vary with concentration. Draw a suitable diagramAns:

is proportional to the amount present. In a certain reaction, the change of the substance satisfies the differential equation𝑑𝑦𝑑𝑡 = -0.64ywhere y is measured in grams and t is measured in hours. If there are 90 grams of the substance when t = 0, how many grams will be left after the first hour?

State the unit of concentration

If 25g of solute is present in 50g of solution. Then calculate % w/W.
