ions (Please show the work for each of the questfons in part y For the following ionic compound, write the symbols for the ions present, and give the number of each: Li CO3. (12 points) 1. 2. You have 180 g of oxalic acid, H2C.204. (5 points each, 10 points in total) What amount (moles) is represented by 180 g of oxalic acids? 1) 2) How many molecules of oxalic acid are in 180 g? 3. The empirical formula of a substance is CH:0. If its molar mass is 120.05 g/imol. What is ti molecular formula of the substance? (12 points) Page

Explanation / Answer

The given compound is Li2CO3

The ions present in this compound are Li+ and CO3-2

The number of lithium ions are = 2 ( Li+)

the number carbonate ions = 1 (CO3-2)
