The density of CaO is 3.35xx10^(3)kg*m^-...

The density of CaO is `3.35xx10^(3)kg*m^-(3)`. This oxide crystallises in one of the cubic system with a = 480pm. Calculate the number of formula units in the unit cell of the oxide. Which type of cubic system is it?

Text Solution

AI Generated Solution

To solve the problem, we need to calculate the number of formula units in the unit cell of calcium oxide (CaO) given its density and the edge length of the cubic unit cell. We will also identify the type of cubic system it belongs to. ### Step-by-Step Solution: 1. **Convert Density to Appropriate Units:** The given density of CaO is \( \rho = 3.35 \times 10^3 \, \text{kg/m}^3 \). We need to convert this to grams per cubic centimeter (g/cm³): \[ ...
