​

Answer 1

A DBMS plays a crucial role in both the creation and management of data. Without a database management system, running and managing data effectively is not possible. Serving as the intermediary between the user and the database, a DBMS provides users access to files stored in a database

Answer 2

Step-by-step explanation:

Molecular mass=2*vapour density

Molecular mass=2*vapour density =2*11.2

Molecular mass=2*vapour density =2*11.2=22.4 g

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 l

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 lvolume of 11.2g gas = 22.4/22.4*11.2

Molecular mass=2*vapour density =2*11.2=22.4 gAt NTP,volume occupied by 22.4 g of gas= 22.4 lvolume of 11.2g gas = 22.4/22.4*11.2= 11.2 l
