Question

Dilutions 

Answer 1

 

 

1% solution is 1 g dissolved in 100 ml.

 

Convert 2400 mg to g.

 

2.4 g is dissolved in 120 ml.

 

Write an equation:

 

2.4 g /120 ml = x g /100 ml -------------- Solve for x

 

x = (2.4 * 100)/120

 

x = 2.

 

It's a 2% solution or 2 g dissolved in 100 ml.
