You have to know how to enter this into your calculator. Step by step: hit the stat button and then edit. Enter your x values one at a time in the first column, hitting enter after each value. When finished with x's, arrow over to the second column and enter each y value in, one at a time, hitting enter after each value. When you're done, hit stat again, tab over to calc and hit enter. You will then arrow down to LinReg(ax+b). Hit enter. If you have a TI 83, then the equation should just generate automatically. If you have a TI84 family, you need to arrow down to "calculate" and then hit enter. Your equation will then generate. It is the last choice above, y = 1/2x + 4. Learn how to use your calculator; it can do SO many cool things for you!!!

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
