Question

5 g of calcium carbonate with 2 g of oxygen to form a compound. find the molecular formula of the compound. (atomic mass of Ca =40u and O=60u)​

Answer 1

Step-by-step explanation:

If ratio of calcium isto oxygen is 5:2 compound formed is 7 grams

Or ratio is 40 :16

The molecular formula will be CaO

2Ca +O2->2CaO
