Answer:
0.9726g/ml
0.9726g/cm³
Explanation:
Density is found by dividing mass by volume.
Density = mass/volume
mass = 7.1g
volume= the new level of water raised - the initial level of water
volume = 32.4 - 25.1
volume = 7.3 ml
Volume is the amount of space occupied by an object.meaning the amount of volume displaced by the object is its volume.
density = 7.1 /7.3
density = 0.9726g/ml
or 0.9726 g/cm³
If you need any clarification or more explanation pls do mention at the comment section.
hope this helps and if it does pls mark as branliest answer thx
The atomic mass of an element is the number of times of an atom of that element is heavier than an atom of carbon taken as 12. In simpler way, atomic mass is number of protons present in nucleus of an atom, which is a characteristic of an chemical element and is determines place of the element in the periodic table. Mass number is total number of protons and neutrons. If an uncharged atom looses electron from its outermost shell, it becomes cation, which is positively charged species. Atomic number and mass number do not change if electron goes out of an atom.
Uncharged copper after loosing two electrons is converted to 
which can be represented as follows:
→
Because if they are submerged in the solvent, they would dissolve! This would prevent them from seperating and not allow you to actually record anything
Answer:
Solute concentration will afect the rate of a chemical reaction, because you must work with molarity
Explanation:
I think that solute mass may be it can affect the rate of reaction, if you have more mass in a solute, you will also have more moles.
If you want to know more, you have to consider temperature in the reaction and the presence of catalysts. They all, affect reactions.
Acid of x bottle is highly reactive because solute is more and acid of y bottle is less reactive because solvent is more.
