A common stain remover is sold in concentrated form as 1.8M sodium hypochlorite (NaOCl). For everyday use, you create 2.2 liter of a more dilute solution by dissolving 0.015 liters of the 1.8M solution in water. What is the concentration of this new solution?

0.012M

0.18M

1.4M

2.64M

$$n_{a}c_{a} = n_{b}c_{b}$$

where n = concentration 
c = volume

photon336 · Answer

$$n_{a} = 1.8M; 0.15L = c_{a}; 2.2L = c_{b}$$

$$\frac{ n_{a}c_{a} }{ c_{b} }  = n_{b}$$

$$\frac{ 1.8~\frac{ mol }{ L }*0.15~L }{ 2.2~L } = c_{b}$$
