Answer:
10% solution volume
=7.5 L
30% solution volume = 2.5 L
Explanation:
assume 10% solution volume is x
So 30% solution volume = 10-x
Required 15% solution= x volume of 10% solution+ (10-x) volume of 30% solution
0.15 * 10L= 0.1 x + (10- x)* 0.3
1.5= 0.1 x+ 3 -0.3 x
0.2 x= 1.5
x= 7.5
10% solution volume is x
=7.5 L
So 30% solution volume = 10-x = 10-7.5= 2.5 L
