Moles of ammonium sulfate = 26.42/molar mass of (NH4)2SO4
= 26.42/132.14 = 0.19 mole.
Molarity = moles of ammonium sulfate/volume of solution
= 0.19/50x10^-3
= 3.8M
Answer:velocity of molecules within a body
Explanation:
Temperature is defined as the average kinetic energy of the molecules of a body. The kinetic energy of a body depends on the velocity of the molecules of the body. When the temperature of a body increases, its particles acquire greater kinetic energy and move at higher velocity. Hence temperature depends on the velocity of the molecules of a body while heat is a form of energy.
Answer:
The Yerkes-Dodson Law suggests that there is a relationship between performance and arousal. Increased arousal can help improve performance, but only up to a certain point.
