Answer:
Molar mass -56.0774 g/mol
There is a way to calculate this
atomic number for calcium is 20
atomic number for oxygen is 8
The molar mass for calcium is 40
The molar mass for oxygen is 16
CALCIUM OXIDE
40. +. 16
=56g/mol
1 molecule = 1×56=56g/mol
2 molecules=2×56 =112g/mol
Answer:
The entity relationship (ER) data model has existed for over 35 years. It is well suited to data modelling for use with databases because it is fairly abstract and is easy to discuss and explain. ER models are readily translated to relations. ER models, also called an ER schema, are represented by ER diagrams.
