Question 102

1.4 g of lithium are reacted completely with water.

The reaction makes a solution of lithium hydroxide.

The volume of this solution is 1.5 dm³.

Calculate the concentration of the lithium hydroxide solution in $dm−3\text{g dm}^{-3}$ .

(Relative atomic mass: $Li=7\text{Li} = 7$ ; Relative formula mass: $LiOH=24\text{LiOH} = 24$ )
