Density is the best property to use, as while multiple different metals could create cubes with the same color, mass, or volume, no different metal could create a cube with the same mass and volume. Density is based on mass and volume, and as a result no two different metals will have the same density.
Answer:
The required new pressure is 775 mm hg.
Explanation:
We are given that gas has a volume of 185 ml and a pressure of 310 mm hg. The desired volume is 74.0 ml.
We have to find the required new pressure.
Let the required new pressure be '
'.
As we know that Boyle's law formula states that;
where, 
= original pressure of gas in the container = 310 mm hg
= required new pressure
= volume of gas in the container = 185 ml
= desired new volume of the gas = 74 ml
So, 
= 775 mm hg
Hence, the required new pressure is 775 mm hg.
find acceleration force divided by Mass

Ionic compounds are made up of two charged species, a cation (+) and an anion (–).
The charges must balance out to zero for a stable ionic compound, because ionic bonds are formed between two charged species. They form in ratios according to their charges to balance out.
