Question

Convert each of the concentrations in part A,B and C, which are in %w/v into w/w. Hint: you need to use the denisitt for each solution.

Explanation / Answer

Formula %w/w = weight of solute/weight of solution * 100

Part A: PURE(0)= 28.2g (%w/w format)

10= 29.1

20=30.1

30=30.5

40=31.3

50=32.2

Part B:code A: 29.6

code B: 30.3

Part C: 14.2
