Step 1: Define

[RxN - Balanced]   MgCl₂ + 2LiOH → Mg(OH)₂ + 2LiCl

[Given]   255 g Mg(OH)₂

[Solve]   x g MgCl₂

Step 2: Identify Conversions

[RxN] 1 mol MgCl₂ → 1 mol Mg(OH)₂

[PT] Molar Mass of Mg - 24.31 g/mol

[PT] Molar Mass of O - 16.00 g/mol

[PT] Molar Mass of H - 1.01 g/mol

[PT] Molar Mass of Cl - 35.45 g/mol

Molar Mass of Mg(OH)₂- 24.31 + 2(16.00) + 2(1.01) = 58.33 g/mol

Molar Mass of MgCl₂ - 24.31 + 2(35.45) = 95.21 g/mol

Step 3: Stoichiometry

Step 4: Check

Follow sig fig rules and round. We are given 3 sig figs.

416.227 g MgCl₂ ≈ 416 g MgCl₂

african americans demonstrated their newly found freedom by relocating often in search of relatives whom they had been separated from during slavery. others established schools to educate freed people and they built institutions such as churches and political organizations to advocate for their rights.

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
