100 g of 20% salt solution is mixed with 200g of 10% salt solution. Find out the concentration of the resulting solution.​
Hoochie [10]

Explanation:

The total mass is:

100 g + 200 g

= 300 g

The mass of salt is:

0.20 (100 g) + 0.10 (200 g)

= 20 g + 20 g

= 40 g

So the concentration is:

40 g / 300 g

≈ 13.33%

Round as needed.
