IMAT 2016 Q47 [Concentration]

A sample of lithium was completely reacted with water. The equation for this reaction is:

2Li(s) + 2H_2O(l) → 2LiOH(aq) + H_2(g)

The aqueous lithium hydroxide solution formed has a concentration of 0.10 mol/L.

What is its concentration in g/L?

(A_r: Li = 7.0; O = 16.0; H = 1.0)

A. 240
B. 480
C. 4.8
D. 3.1
E. 2.4
