ram prepared two aqueous solutions of sugar i.e., 'A' and 'B'. he prepared 150 ml of solution 'A' with concentration 30% (w/V) and 200 ml of solution 'B' with concentration 40% (w/V). he mix solution 'A' and 'B'. identify the concentration (w/V) of solution formed after mixing.

Answer:
1 ml concentration A = 30/100*150
= 45 w/V
1 ml concentration B = 40/100*200
= 80 w/V
Resulting concentration
30/150 + 40/200
= 1/5 + 1/5
= 2/5
= 40% w/V
