Answer:
<h3>The answer is 11 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 3025 g
volume = 275 mL
We have
We have the final answer as
<h3>11 g/mL</h3>

Answer:
Thus, molar volumes of the liquids are expected to be closer to those in the "solid state."
Explanation:
Anything which occupies mass is known as the matter and we know that matter is existed in three states i.e. solid, liquid and gas. The atoms in the solid are closely packed and therefore, they posses very less kinetic energy. The atoms in liquid state are less closely packed and possess more kinetic energy in comparison to the solid state. The atoms in the gaseous state are loose and possess maximum kinetic energy. The molar volume is the volume occupied by 1 mole of a substance. Solid being compressed will have lesser volume in comparison to the liquid and liquid will have lesser volume in comparison to the gas.
In the solid state, it is expected that the amount of empty space is less than that of the gaseous state, and molar volumes are influenced by molecular characteristics. Thus, solid state molar volumes are not similar to those in the gaseous state. When, comparing empty space in the liquid state, it is expected that space in the liquid phases is less than space in the gaseous phase and equivalent to space to the solid state. Thus, molar volumes of the liquids are expected to be closer to those in the solid state.
Option No. 1 at the cathode in both an electrolytic cell and a voltaic cell
Negative ion arrives at the anode, attracted by electrostatic forces, where they lose electrons. Loss of electrons is defined as oxidation.
The reverse process occur at the negative electrode, where positive ions pick up electrons. They are reduced.
