Question

At STP 11.2L oxygen is needed to convert a 6g solid element 'A' to its gaseous oxide completely. If the volume of that oxide produced be 11.2L at STP, find the molecular mass of that oxide.[O = 16] Please slove this sum please..........​

Answer 1

Answer:

Explanation:

A + 02 --------> A0

6g     11.2L            11.2L

11.2 -------- 6g

                     22.4 -------- 12g

molecular mass = 12+16 = 28
