As a result, when a substance absorbs enough energy then its atoms or molecules move around. And, when increase in this energy takes place then atoms tend to collide frequently with each other. Hence, it causes change in state of a substance. Therefore, changes in matter are important for the conservation of energy

Hey there!
Mass of NaCl = 4.78 g
Molar mass of NaCl = 58.44 g/mol
Volume of solution = 12.34 mL
Number of moles:
n = mass of solute / molar mass
n = 4.78 / 58.44
n = 0.08179 moles of NaCl
Volume in liters:
12.34 mL / 1000 => 0.01234 L
Therefore:
Molarity = number of moles / Volume ( L )
Molarity = 0.08179 / 0.01234
Molarity = 6.62 M
Hope that thelps!
Answer: Deriving from ancient Chinese myths and folklores, a fox that lives a thousand years turns into a kumiho, like its Japanese and Chinese counterparts. It can freely transform, among other things, into a beautiful woman often set out to seduce boys, and eat their liver or heart (depending on the legend).
Hoped that helped!
