<u>Step 1: Define</u>
0.41 mol CaO
2.5 M Solution
<u>Step 2: Identify Conversions</u>
1000 g = 1 kg
Molar Mass of Ca - 40.08 g/mol
Molar Mass of O - 16.00 g/mol
Molar Mass of CaO - 40.08 + 16.00 = 56.08 g/mol
<u>Step 3: Convert</u>
- Set up:

- Multiply:

<u>Step 4: Check</u>
<em>Follow sig fig rules and round. We are given 2 sig figs as our lowest.</em>
0.024114 kg CaO ≈ 0.024 kg CaO
Usually, a model is a depiction of a certain entity, never the real thing. In times
past, many, many models look great on paper but are way off!
Bleach would increase the pH because Bleach is a basic substance with a pH of about 12
Soda would lower the pH because the pH of sodas is somewhere around 2.5 (this is for coke, other sodas are a bit different)
