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:

44 g

Explanation:

22.4 L of any gas at STP weighs equal to its molecular mass. Here 11.2 L of the gaseous oxide weighs = 22 g according to the balanced chemical equation. So, 22.4 L of the gaseous oxide will weigh = 44 g which is the molecular mass of the oxide.
