R - 2k = 15...subtract r from both sides
-2k = 15 - r ...divide both sides by -2
k = (15 - r) / -2 or k = -7.5 + (r/2)

Step-by-step explanation:
Collect the molar masses of each element contained in LiOH.
- Lithium (Li) has a molar mass of 6.941 g/mol
- Oxygen (O) has a mass of 15.999 g/mol
- Hydrogen (H) has a mass of 1.008 g/mol
Together, LiOH has a molar mass of 23.948 g/mol.
Convert the given amount of LiOH from g to mol:
(67.03 g) * (1/23.948 mol/g) = 2.799 mol
