Answer:
0.29 mol/L
Explanation:
Its density is 1.029 g/ml so in a liter (1000 mL) there is 1029 g of solution, but only 5% is dextrose.
0.05x1029=51.45
So in a liter of D5W solution there is 51.45 g of dextrose.
Dextrose molar mass iss 180.156 g/mol, so in 51.45 g of dextrose there is
51.45/180.156=0.29 mol
In one liter of solution there is 0.29 mol of dextrose, so the molarity of such solution is 0.29 mol/L.

In physics, energy is a quantitative property that is transferred to a body or physical system and can be perceived in the performance of work or in the form of heat and light. Energy is Conserved - The law of conservation of energy states that energy can be transformed into form, but cannot be created or destroyed.
Energy, in physics the ability to do work. It can exist in electrical, kinetic, thermal, electrical, chemical, nuclear, or various other forms. There is also heat and work. H. Energy in transfer from one object to another. Ability or power to do work. B. The ability to move an object (of a certain mass) by applying a force. Energy exists in many forms, such as electrical, mechanical, chemical, thermal, and nuclear, and can be transformed from one form to another.

I believe your answer is Plate Tectonics! Hope that helps! :D
Answer:
False
Explanation:
The term was first "officially" used by French physicist Jean Baptiste Perrin. He technically referenced the works of Avogadro
