Answer:
If you have a solution, you multiply the molarity by the volume in litres. There are two steps: Multiply the volume by the density to get the mass. Divide the mass by the molar mass to get the number of moles.
Answer:
The percentage yield is= 80%
Explanation:
% yield= actual yield/theoretical yield ×100
From The question
Actual yield= 240mg
Theoretical yield= 300mg
%yield= 240/300×100= 80%
Answer:
A
Explanation:
The molecules in both metal and surrounding air will start moving slower because of the sudden decrease in environment tmeperature. The thermal energy around the metal plate decreases, also decreasing the kinetic energy.
