Question

An experiment shows that 13.88g of

Calcium choride were obtained from the combination of 5g of Ca with chlorine what is the empirical formula of the compound?
​

Answer 1

CaCl₂

Step-by-step explanation:

Mass of Calcium chloride = 13.88g

Mass of Ca = 5g

So,

Mass of chlorine = 13.88g - 5g = 8.88g

Now;

Empirical formula of the compound;

The empirical formula is the simplest formula of a compound;
