M(KNO₃)=101.1 g/mol
M(CO(NH₂)₂)=60.1 g/mol
m(N)=M(N)m(KNO₃)/M(KNO₃)
m(N)=2M(N)m(CO(NH₂)₂)/M(CO(NH₂)₂)
2m(CO(NH₂)₂)/M(CO(NH₂)₂)=m(KNO₃)/M(KNO₃)
m(CO(NH₂)₂)=M(CO(NH₂)₂)m(KNO₃)/(2M(KNO₃))
m(CO(NH₂)₂)=60.1*101.1/(2*101.1)=30.05 g
because the model makes the concepts easier to understand
Explanation:
A model would be useful because they make concepts easier to understand.
Models are abstractions of the real world.
- Scientists use model to make concepts easier to understand
- Models take parts of the real world and simulates them.
- They help remove the ambiguity that might be associated with studying the real world.
