Answer:
Bathtub
Explanation:
Even though the water in a filled bathtub may be at the same temperature as water in a glass, the water in the bathtub has more thermal energy because it contains a greater number of water molecules.
Answer:
1.13 M
Explanation:
Given data
- Mass of luminol (solute): 15.0 g
- Volume of solution = volume of water = 75.0 mL = 0.0750 L
- Molar mass of luminol: 177.16 g/mol
The molarity of the stock solution of luminol is:
M = mass of solute / molar mass of solute × liters of solution
M = 15.0 g / 177.16 g/mol × 0.0750 L
M = 1.13 M
It should be Carbon Nanotubes
