Answer:
Option C. 1M
Explanation:
From the question given, we obtained the following data:
Mass of LiOH = 12g
Volume = 500mL = 500/1000 = 0.5L
Molarity =?
To solve for the molarity, we need to find the number of mole of LiOH.
This can be achieved by:
Molar Mass of LiOH = 7 + 16 +1 = 24g/mol
Number of mole = Mass /Molar Mass
Number of mole of LiOH = 12/24 = 0.5mol.
Now we can find the molarity as follows:
Molarity = mole /Volume(L)
Molarity = 0.5/0.5 = 1M
