can i have brainiest
The two samples will have the same density because they are the same substance. The volume will have increased just enough to balance the greater mass. Key Concept- When substances have the same volumes but different masses, the substance having the greatest mass will be the most dense.
For the answer to the question above asking, h<span>ow many moles of glucose (C6H12O6) are in 1.5 liters of a 4.5 M C6H12O6 solution?
The answer to your question is the the third one among the given choices which is 6.8 mol.

Answer:
Explanation:
First of all we need to calculate the heat that the water in the cooler is able to release:
Where:
- Cp is the mass heat capacity of water
- V is the volume
is the density
To calculate the mass of CO2 that sublimes:
Knowing that the enthalpy of sublimation for the CO2 is:
