A mineral containing calcium, oxygen and titanius crystallises in a given cubic unit cell. What is the formula of the mineral?

Explanation

To determine the formula of the mineral containing calcium, oxygen, and titanium that crystallizes in a cubic unit cell, we can follow these steps:

### Step 1: Identify the elements and their common oxidation states
- Calcium (Ca) typically has an oxidation state of +2.
- Oxygen (O) typically has an oxidation state of -2.
- Titanium (Ti) can have multiple oxidation states, but in many minerals, it is commonly found in the +4 oxidation state.

### Step 2: Determine the ratio of the elements based on their oxidation states
